Create Sub Element, with basepoint in another
floor
Annotation to Floor and TopoSurfaces
Modify Floors
Define slope
|
|
In the
Ribbon New Sub Element, the slope must be typed in percentage %
(+ Enter). A positive number will create a decreased slope, negative numbers
will create an increased slope |
Default Floor
|
|
If
there is a lot of work in one specific floor, the function Default Floor can
save a lot of selecting. If a Default
Floor is selected the step” Select the floor to modify” can be
ignored. When
working in other floors than the Default Floor, the function must be reset or a new floor must be selected as Default Floor. |

|
2:
Select the floor in which to create the new Sub Element Floor(1) (Default Floor) 3:
Select the floor where the basepoint is located Floor(2) 4:
Select the basepoint for the calculation
The selected point must be a Sub Element or a point on a line.
If the selected point isn’t a Sub Element the user will be prompted to select if the nearest point is to be
used as basepoint or to create a
new Sub element 5:
Select the position for the new Sub Element Point(2)
|
|||
|
|
The
user will be asked if a new Sub Element is to be created where the line
between the basepoint and the placement for the new Sub Element intersect
with edges of the two floors Point(3) Note: If the
two floors do not intersect the point will not be created. |
|||
|
TIPS:
|
If a
plane slope is wanted on floor(2) the point(4) It can
be set to the same elevation as point(3) by typing
the slope 0 and insert a new Sub element in point (4), with point(3) as base
point. |
Match Sub Elements
|
|
Two floors sharing the same edges can be modified so the Sub Elements
will have the same elevations, or with the same distance in elevations. 1: Type the elevations offset 2: Select the floor with the right elevation 3: Select the floors to be modified |
Adjust Sub Elements
|
|
The
Sub Elements will be adjusted with the distance typed in the Offset in mm box 1: Type the elevations offset 2: Select the floor(s) in which to adjust the Sub Elements 3: Press Finish (selection) in the upper left corner 4: Draw a window around the Sub elements to Adjust |
Match Floor to element
|
|
This
function will set the elevation on all the endpoints in the floor boundary
lines. The
elevation will be set to match the selected imported object in the same or
nearest point (max. 50 mm). The
offset value will be used to calculate the new elevation. 1: Select the “source” element 2: Select the floor(s) in which to add the vertex Note: Some Blocks/Cells in the DWG/DGN files may cause
an incorrect elevation. Therefore they must
be removed/exploded before loaded into Revit. It is
very important that the dwg only contains the lines/solids, you want to
connect floors to otherwise you can get an incorrect elevation. |
Match Point to element
|
|
This
function will be crated a Floor vertex in the selected point with the
elevation from the selected imported object in the same or nearest point
(max. 50 mm). The
offset value will be used to calculate the new elevation. 1: Select the “source” element 2: Select the floor(s) in which to add the vertex 3: Select the points where you want the new vertex The function will be repeated until “Esc” is pressed. Note: Some Blocks/Cells in the DWG/DGN files may cause
an incorrect elevation. Therefore they must
be removed/exploded before loaded into Revit. It is
very important that the dwg only contains the lines/solids, you want to connect floors to otherwise you can get an incorrect
elevation. |
Match curbs to element
|
|
This
function will change the elevation of the endpoints of the selected Curbs, or
any other family from the category “Structural framing”, to the elevation
from the selected imported object in the same or nearest point (max. 50 mm). The
offset value will be used to calculate the new elevation. 1: Select the “source” element 2: Select the curb(s) in which to add the vertex 3: Select the points where you want the new vertex The function will be repeated until “Esc” is pressed. Note: Some Blocks/Cells in the DWG/DGN files may cause an incorrect
elevation. Therefore, they must be removed/exploded before loaded into Revit. It is
very important that the dwg only contains the lines/solids, you want to
connect floors to otherwise you can get an incorrect elevation. |
Unify Slope
|
|
1:
Select 2 Sub Elements and a point in a line The
slope between the two selected Sub Elements will be registered and the
elevation in the 3rd point is calculated. If the
3rd point is a Sub Element the elevation is changed. If the
3rd point isn’t a Sub Element the user will be prompted to Create
a new Sub Element. |
Match Floor to Grating
|
|
Match
Floor to Grating will create Sub Elements around a Family to match
the Family`s elevation. 1:
Make sure the family is in the right elevation 2:
Select the Family 3:
Select the Floor (If the Family isn’t hosted in the floor) Note: If a
Yes/No Parameter named ”Circular” is present and
checked in the Family the function will create 16 Sub Elements around the
family. If the
parameter isn’t in the family or is unchecked the family is considered a
square and 4 Sub Elements will be created around the family. |
Sub Elements in real Levels
|
|
The
Sub Elements in the selected floors will be set to real Levels and the floor
will keep the attachment to the Level. 1:
Select the floor(s) in which to adjust the Sub
Elements 2:
Press Finish (selection) in the upper left corner Notes: If the
Sub Elements in the floors have been reset, the offset From Level, must be
set to 0 to get the floor in the right position again. Placing
a new Sub Element after using this function: Set the Elevation to 0 and then
correct the elevation on the Sub Element. |
Infill Floor, Create / Update
|
|
InFill Floor create floors inside selected openings. These
openings must be vertical openings and drawn independently (two
openings drawn in the same sketch will not work). Create. The
openings can be selected one by one or with a Window/Crossing selection. If no
openings are found in the section, LTM will search for openings in the selected
floors. Select
a FloorType for the Infill floor. Select
“Include inner SubElements” if the sub-elements
from the main floor, placed inside the openings, must be added to the infill
floor. Update. Update
the Infill Floor to the geometry of the opening if it is modified. Tip: Add or
remove the inner SubElements, check/uncheck the
“Include Inner SubElemnts” on the InFill Floor, before updating. |
Annotation to Floor and TopoSurfaces
|
|
Annotation
on Floor and Toposurfaces, is converting Sketch
annotation into vertexes on Floors and/or Toposurfaces. 1: Select the Floors and Toposurfaces to place the new vertexes on. 2:
Press Finish (selection) in the upper left corner. 3:
Select the Annotations to convert. 4:

floor on the lowest horizontal bottom face of the selected element. 1:
Select the element you want to create the floors 2: Select floortype. |
Filled Regions
Create Filled Region
|
|
If
the floor has different slopes the graphical presentation in Revit isn’t
always useful. Create
Filled Regions to compensate. 1:
Select the floor 2:
Select the filled Region Type. The
Filled Region is created with the same extension as the floor. The
Floor and the Filled Region will be connected to use the Updated Filled Region. The
Surface pattern will be turned off on the selected floors If the
opening touches the bounding line of the floor. It is important that the line
of the opening and the bounding line of the floor is aligned. Note: Filled
Regions not created by the function Create Filled Region in this APP,
will not response on the function Update Filled Region |
Clone Filled Region
|
If one
or more Filled Regions are created in one view and the same Filled Region
connection to the same floors is wanted in a new view, use the Clone Filled
Region Function. 1:
Make sure the view to create the Filled Regions
is Active 2:
Select the view from where the Filled Regions
must be cloned. To
keep the connection between the filled Region and the floor to use the Update
Filled Region, it is important to use his command instead of copy the Filled Regions |
Update Filled Regions
|
|
If one
or more floors are changed to another extension, the Filled Region (created
by the create Filled Region function) can by updated by following the floors
new extensions. By
selecting Update Filled Regions, All Filled Regions in the project
with be updated to the floors extension to which they are connected. Note: By
using the Update Filled Regions Function any changes in the filled region, e.g. Rotation or moving the pattern will be reset. Tip: To
find the right place for the pattern in the Filled Regions after the use of
Update Filled Regions Draw
one or more refplanes where the pattern is located.
Use
the Align command to align the pattern to the refplanes. Use Update
by Selection to update only the selected Filled Region |

function will place a Spot Elevation. 1:
Select if you want to create or delete spot elevation 2:
Select the Floor(s) on which you want Spot elevation 3:
Press Finish (selection) in the upper left corner. Note: The
function will use the default Spot Elevation Tag. Insert
a Spot elevation manually to change the default. |
Sketch Annotation
|
|
The
Sketch Annotation is a set of tools to make 2D Sketch Annotation for
elevations. These commands require the use of special Families “Sketch_Elevation_Annotation_DK” & “Sketch_Elevation_Annotation_UK” are located at: C:\ProgramData\Autodesk\ ApplicationPlugins
\LandscapeTerrainModeller.bundle\
Contents\Resources, or you can use families and location from your company.
(Look at “Create Sketch Annotation”). Note: The
new elevations will use the number of digits from the first selected
elevation. The
functions will run in loop until you press esc. These
Functions will NOT be automatically updated if the geometry changes or the
annotations are replaced. |
|||
|
|
Sketch New Annotation, creates a new Annotation, with a new elevation written. Select an Annotation and pick the position for the new annotation. The new elevation will be calculated using the slope in the LTM Menu. |
|||
|
|
Sketch Interpolation calculate
a new elevation between two Annotations. Select First & Second Annotation and the placement for the new
annotation, between or continuation of the two annotations. |
|||
|
|
Sketch Slope, add a text between two annotations showing the slope and direction. Select the two annotations and the placement for the slope text. Note: This
function is only available in floorplan oriented in project north, or where
true north is aligned with Project north. The function will use the default Text type or the TextType
added at “Settings” |
|||
|
|
Adjust Sketch elevation Select the Sketch Annotations you want to adjust, with the value in
the LTM “Offset” menu |
|||
|
|
Update sketch Slope, will update the Sketch slope annotations. The function can be used if some of the elevations have changed, it
will update the slope from the new elevation. The texts are updated to the current text style. Note: This
function is only available in floorplan oriented in project north, or where
true north is aligned with Project north. |
|||
|
|
Place New Annotation Place a new Sketch Annotation and type the elevation in the dialog
box. The family Type can be set in the Settings menu. Note: If the elevation contains “,” or “.” the elevation will be calculated
in meter if not it will be calculated in millimetre. |
|||
|
|
Place New Annotation 3D Place a new Sketch Annotation, the elevation will be set from the
selected object 1:
Select the imported object you want to get the elevation from 2:
Select the points to place the Sketch elevation. The family Type can be set in the Settings menu. Note: Some Blocks/Cells in the DWG/DGN files may cause
an incorrect elevation. Therefore they must
be removed/exploded before loaded into Revit. It is very important that the dwg only contains the lines/solids, you
want to connect floors to otherwise you can get
an incorrect elevation. |
Slope text on faces & edges
|
|
Slope
text on faces & edges will place text notes on faces and/or edges on the
Floors. 1:
Select if you want to create or delete text notes 2:
Select the Floor(s) on which you want slope texts 3:
Press Finish (selection) in the upper left corner. The
first time this function is used in the model 2x2 parameters are loaded and
attached to floors. Minimum_Slope Minimum_Slope_Type & Maximum_Slope Maximum_Slope_Type For
each Floor Type or Instance you can type in a
Minimum and/or a Maximum slope. If the
slope is less than the value in Minimum_Slope(_Type)
the texts will be red. If the
slope is greater than the value in Maximum_Slope(_Type),
the slope texts will be orange.
next time the function is used (The colors can be changes in the settings panel) If
there are values in both e.g. Minimum_Slope
and Minimum_Slope_Type the value from the instance,
Minimum_Slope will be used. When
the function is used again the old slope texts will be deleted. Note: This
function is only available in floorplan oriented in project north, or where
true north is aligned with Project north. The
Slope Texts are for QA only and they will NOT be automatically updated if the
Floor geometry changes. The
function will use the default Text type or the TextType
add at “Settings” |
Model Lines
|
This
set of functions gives the possibility to create model lines from imported
dwg files, modify those model lines, annotate them
and create toposurface from them. 1.
Import Lines 2.
Change Style & Elevation 3.
Offset Lines 4.
Elevation Texts 5.
Elevation Info 6.
Set New Elevation 7.
Create Toposurface |
|||
|
|
1.
Import Lines Import Lines creates model lines in Revit from a linked .dwg file. The
name of the AutoCAD layers in which the elevation lines were will be given to
the model lines style in Revit. Check Include LineType__0.5 to add “_0.5” at the end of the
line type’s name. It will only be added to the lines standing at an elevation
finishing by 500 (1500, 2500, 10500…). Check Include LineType__5 to add “_5” at the end of the line
type’s name. It will only be added to the lines standing at an elevation
finishing by 5000 (5000, 15000, 25000…). Check Create associated named refplanes
to create a reference plane for each model line elevation. The reference planes
will be named after the elevations and can be used as work planes (to place modellines, objects, etc. at a
specific elevation) Check Flatten to level if the model lines must be placed on
active level, This function is only active in planview. Note: Do not scale up/down the dwg file before or after linking it in Revit.
The units in the dwg file must be defined (meters, millimeters…). |
|||
|
|
2.
Change Style & Elevation
Use Change Style & Elevation to copy and paste the properties of a
model line. The line style and elevation will be copied. Click once on the line to copy the properties from. Then select
all the lines to paste the properties to. Click finish. |
|||
|
|
3.
Offset Lines Use Offset Lines to create elevation lines every 500 mm between
two other elevation lines. The chosen lines can either be from the imported model lines or can be
drawn manually. There must be a difference of elevation between the
two lines or nothing will be created. Click on Offset Lines, select the first line, then the second at a
higher or lower elevation. |
|||
|
|
4.
Elevation Texts Use Elevation Texts to tag the elevation of the model lines. Draw a virtual line (place the start point, then the end) to define
which elevation will be tagged and where. A text
will be placed at every intersection between the “virtual line” and the
elevation lines. |
|||
|
|
5.
Elevation Info Use Elevation Info to know and eventually tag the elevation of a model
line. Click on Elevation Info then click on a line: the elevation will be
written on the bottom left corner of Revit. Click again to place an
elevation tag or press Esc to exit. |

Create Toposurface Use Create Toposurface to create a toposurface from the selected model
lines. Click on Create Toposurface then select the model lines and
click Finish on the top left corner of Revit. |
TopoSurfaces
TopoSurface to Floor
|
This
function will convert a Topography into a Floor. 1:
Select a Topography 2:
Select a Floor Type from the list Note: The
Sub Region must be inside the Topography. Boundary
loop inside another loop, can make the Floor unstable, use opening instead. Building Pads are ignored by this function |
Buildings
on Toposurface
|
|
Buildings
on TopoSurface adjust the Z value on the selected objects to match the
Toposurface. Select
the placement and write an Offset (Z) if needed. If you
want to regulate the terrain around the building, check the Regulate Terrain,
checkbox. Write
the wanted offset around the building. Note: If it
is a linked model containing a Filled Region, with the value Gross Area, in
the property Comments, LTM will use the boundary lines from this Filled
Region as basis to the terrain regulation otherwise the bounding box will be
used. |
Other commands
Cut/Fill, SubSoil
|
|
Cut/Fill
Subsoil calculates volumes of subsoil to add (fill) or remove (cut). The
first time the Cut/Fill Subsoil is used in a model, LTM will load: -
2 parameters (TopSoil and SubSoil) attached to TopoSurfaces -
3 parameters (SubSoil_Cut,
SubSoil_Fill & SubSoil_Total)
attached to Property lines -
the property line TAG “A-Cut_Fill
TAG.rfa”. You
must indicate if the TopoSurface represents the TopSoil
or SubSoil before running the calculation. There
are 3 precision levels for the volume calculation: low, medium
and high. The TopSoil must be modelled as an Existing
TopoSurface with the parameter “TopSoil” checked. The SubSoil can be modelled as an Existing TopoSurface with
the parameter “SubSoil” checked. Or The SubSoil can be indicated as a distance from the TopSoil when using the function. The
function will calculate the volume (Cut/Fill) between the SubSoil
and the bottom of the objects. The
calculation result is stored in the Property lines and can be shown with the PropertyLine TAG “A-Cut_Fill TAG.rfa”. |
Objects on Lines
|
|
Objects on Lines will place families on the selected lines, the
families can be placed in different ways. 1: Select the lines you want the families to be placed along. (Splines
will not be included) 2:
Select the family. If the
family isn´t placed on start of the lines, you must select a point to mark
the start on the Line. When the lines are selected, the numbers and total length is shown
below the select button. When the family is selected the name is shown below the button. There are 4 ways to place the families. The numbers of objects or distance must be written in the textbox. Max distance per line, will place the objects
with a max distance on each line (If the line is longer than the distance). Objects per Line, will place the written number of objects on each line. Fixed distance Total, will place the objects with the written distance on the selected
lines. Max distance Total, will place the objects with a max distance on the selected lines. Place Objects 3D, will adjust the place objects on the Floors or Toposurfaces
they are placed on. Align Object to curve, will rotate the object
to match the direction of the line they are places on Place Object at start of line, will
place an object at the start on each line Place Object at the end of the last line, will
place an object at the end of the last line Degrees Rotation, will rotate the object before placing, e.g. if the object must be
placed perpendicular on the lines instead of along the lines. Group Objects will group all the placed objects, and can be named
using the textbox below the checkbox Group Lines will group all the selected lines, and can be named
using the textbox below the checkbox Some of the options can be combined, e.g. if
you want 3 objects on each line and one on the beginning on each line and
perhaps an object on the end of the last line. Additions features: If the selected object is an annotation, used for elevation texts, the
elevation will be calculated (using the slope written in the LTM menu). If the parameter “Length” is attached to Groups, the total length of
the selected lines will be written into it. (If the “Group Line” is selected) If the selected object contains the Parameter “Length” the distance
from the start point will be written to it. |
Find Coordinate
|
|
This
function will create a cross on a specific coordinate 1:
Type in coordinate values for both directions 2:
Change the size of the cross, if necessary |
Import/Export
DXF export
|
|
This
function will create a DXF file, with all the edges in the active view as 3D
lines e.g. for importing in Microstation OpenRoad, or Mike Urban. |
|||
|
|
You
have several options for the export: Export
all objects in the active view, or selected objects. Export
Type: Select Lines or faces. Floor
Layers: (Only if Lines are selected as export type). “Incl.
Bottom” The export will contain lines for the top surface and the bottom
layers. By
“Incl. Layers”, the export will contain lines for each layer in the floors. If
nothing is selected, only the top layer will be exported. |
|||
|
|
When
3D lines are imported in software to create faces, they will normally not
allow points or lines in the same position but with different height (Z
value) If
floors around a retaining wall are exported this situation will appear,
therefore if walls are exported, only the top face will be exported and the
upper face will be offset to avoid this problem. In the
same way, if the model will be used in a calculation in another software,
that eg. need the groundfloor
level to be models as well, it can be done with Floors. If the
FloorType have a checked Yes/No parameter called “FaceOffset” (the Parameter name can be chaged in the settings menu) and the floor are horizontal
without any vertexes, the boundary lines will be exported with the same
offset as the wall top face. If
floors are modelled close to imported objects it is very important to keep a distance of eg. 10 mm to the object to avoid the “Points in same point
but different elevation” issue |
|||
|
|
Naming
of exported layers. All
the layers in the DXF file will be named according to the object they are
created from. Default
export settings: Line/Faces
created from Floors will get the Family Name, Faces created from TopoSurfaceses will be placed on the Layer “Surface” If the
Parameter DXF_Export_As is attached to the object
(as instance) and the value is not empty, the value will be used as layer
name in the DXF export. If the
Parameter DXF_Export_As_Type is attached to the
object Type (Floors and Walls only) and the value is not empty, this value
will be used as layer name in the DXF export. The DXF_Export_As_Type value will only be used if the DXF_Export_As value is empty. If the
floor layers are exported, they will be named with the “floor name” ”Material of the Layer” the bottom of the
floor will be named: “floor
name” ”Bottom” All the
interior break lines will be named as written above with “_int” added in the
end of the name. Note: In
this Export manual the parameter names DXF_Export_As
and DXF_Export_As_Type are
used, they can be changed in the settings menu. DXF
has a max of 30 characters in the file name that means that additional
letters will be ignored. A DXF
Layer can’t begin with a number, if the Layer Name does that, there will be
added a “_” in the beginning to avoid that problem. In the
same way special characters will be replaced with “_” in the layer name. |
Export Annotations To CSV
|
This
function will export the values and the position of Sketch Annotations into a
csv file. 1:
Select the Sketch annotation you want to export, if nothing is selected, all
the annotations in the active view will be exported. 2:
Select path and name for the export csv file. |
Import data
|
This
function will import “points data” from different kind of data formats in
different ways into Revit. 1:
Select the way to import points (Different ways to use
the imported data) 1.1 As sketch Annotation, (Floorplan only) will place a Sketch annotation from each point in the file, in the
active view. Select the Family Type to place. 1.2 To Existing Toposurface, you
will be asked to select the toposurface you want to add point to. 1.3 As New Toposurface, this will create a new toposurface. 1.4 Vertexes in Floors, you will be asked to select the floor you want to
add point to. 2:
Select Filtering of Points (different ways of
sorting the points before importing) 2.1 All points in the
File 2.2 Points inside a rectangle. If you only want points inside a rectangle (Select the two diagonal
corners with “left click” on the mouse). 2.3 Points inside Property
Line. You will be asked to select the Property Line. 2.4 Selected Floors only
points inside the selected floor will be imported. Points inside Sketch Lines. (Floorplan only) 2.5 Draw lines and end with “ESC” (Floorplan only). 3: Check the parameter indicating if it is an existing elevation point. 4:
Select the import file. (on the bottom to the right) If an
imported dwg file is selected before using the import function, all the block
names in the file are listed. Select the name(s) of the elevation points and
all their inserts points are ready to import: The
total numbers of the selection are written instead of the import file. Notes: In
some cases floors and property lines can’t be used
to filter the points. In that case the elements boundary will be used. Use
the Revit function “Import instance Query” to find the block name of the
elevation points. 5:
Select units. Select units for coordinates and elevation (The
first 3 lines in the file will be shown) Units
are disabled if you are using points from a dwg file |
||||||||||||||||||||||||||||||||||||
Analyze
|
|
Analyze, Slope Slope will color
all the upper faces with a slope on the selected objects. Note: If any
objects are selected, the objects are used for the analysis. The colors for “Slope Small” and “Slope Large” are used, they
can be set in the settings panel. |
|||
|
|
Analyze, Slope Min/Max Slope will color
all the upper faces that don’t match the conditions in the parameters “Minimum_Slope” and “Maximum_Slope”
on the selected objects. Note: If any
objects are selected, the objects are used for the analysis. The colors for “Slope Min” and “Slope Max” are used, they can
be set in the settings panel. |
Settings
|
|
Settings: At the “About” dialog select
“Settings” |
|
|
Annotation Text Type: Set the text Type to use at the
functions: Slope Text on Faces and Edges and Sketch annotation. Annotation spotelevation
Parameter name,
is the name of the parameter where the Elevation is written, if the field is
empty, the name “ElevationText“ is used. Annotation ‘Existing’
Parameter name, is the name of the parameter used
for marking if the elevation is existing. If Place Slope Text at Center is checked, the slope text will be placed
automatically right between the two elevation points. If it is uncheked you must select a placement for the text. Family type for sketch Annotation, is the family type used
everywhere the Sketch annotations placed. DXF Export as Name, the name of the (text)parameter
if you want another layer name on the floor/Wall than the type Name in the
DXF export function. DXF Export as Name_Type
the name of the
(text)parameter if you want another layer name on the floor/Wall TYPE than
the type Name in the DXF export function. Parameter Name (Offset) the Name of the (Yes/No)
Parameter to indicate if the face must be offset in the DXF export. Colors Press the square to set the colors for analyzes. Slope Min and Slope Max, is for
the analysis Slope Min/Max that uses the parameters Minimum_Slope and Minimum_Slope_Type on the floors Slope Small & Slope Large is
for slope analyze |
Create Sketch Annotation
|
|
Some of the functions are using a
2D Annotation for Spot Elevations. It is possible to make your own
families. Sketch Annotation must have a
Parameter called “ElevationText” or a parameter
defined in the settings menu of the ParameterType
“Text” where the elevation must be written. If the Parameter is called another
name, it must be written in the Settings Textbox, “Annotation spotelevation Parameter name” The functions will do the
calculation of elevations based on the insert point in the family. If the text contains a comma (“,”)
or a fullstop (“.”), the elevation will be calculated
in meters, if not the elevation is in millimeter. All characters but numbers, “,” “.” & “-“ (In case of negative elevations)
will be ignored of this function, eg. if you want
to set prefix with letters or () it is OK. |
Create Crubs Family
|
|
The function “Match Crubs to element” requires the crubs
to be created in the category “Structual Framing”,
because those families have the availability to use 3D snapping when the are placed and they can be adjusted differently in
each end. |
Other:
Known issues:
- The functions will only work on Floors.
- Floors and openings must only be created in one closed loop.
- Floors with complex geometric forms can cause LTM not to compute.
- Some Topographies with complex forms can make it impossible to create
the floor or edit the floor boundaries. Alternatively, these can be divided
using Split Surface to avoid very large complex floors.
- Some Openings with complex forms or to many edges, can make it
impossible to create InFill floors.
- The DWG file used in the function Import Model must NOT be scaled inside
Revit
- Some Blocks/Cells in the DWG/DGN files can give a wrong elevation,

- It is very important that the dwg only contains the lines/solids, you
want to connect floors to otherwise you can get
an incorrect elevation.
