22 If you need to generate spaces within boundaries that already contain a space, select Yes for Allow
overlapping spaces.
By default, you cannot generate a new space in a boundary that already contains an existing space. However,
a situation can arise where you want to establish an interference between 2 spaces and therefore need to
generate a space within a boundary that already contains a space.
23 Expand Component Dimensions.
24 Specify the geometry type of the space tool:
Then… If you want to…
select 2D from the list. create an associative 2D space tool
select Extrusion from the list. create an associative extruded 3D space tool
select Freeform from the list. create an associative 3D freeform space tool
Defining the extrusion height in the space tool
25 If you have selected Extrusion or Freeform for Geometry type, enter the parameters for the height of the
space tool:
Then… If you want to…
enter a value for Overall Space height.
This value can be defined only for extruded 3D spaces. For 3D
freeform spaces, it is defined by the bounding geometry. specify the overall height of the space, including floor to
ceiling height, ceiling and floor thickness, and space above
ceiling and below floor
enter a height value. specify the ceiling height of the space
enter a value for Floor thickness. specify a floor thickness
enter a value for Ceiling Thickness. specify a ceiling thickness
enter the appropriate value for Height above Ceiling.
This value can be defined only for extruded 3D spaces. specify the distance between the top of the space ceiling
to the top of the space
enter the appropriate value for Height below Floor. specify the distance between the bottom of the space
floor and the bottom of the space
enter a value for Default Surface Height.
This value can be defined only for extruded 3D spaces. For 3D
freeform spaces, the surface height is defined by the bounding
geometry. specify the combined height of ceiling height, ceiling
thickness, and height above ceiling
26 Select one of the following options for Justification to specify the vertical position of the space insertion
point relative to the space:
■
Top of floor
■
Bottom of floor
■
Bottom of space below floor (available only if the height of the space below the floor is bigger than 0)
This value can be defined only for extruded 3D spaces.
27 If you have selected to generate a 3D freeform space, define the 2 calculation cut planes under Advanced
Dimensions.
28 Click OK.
