Creating Slice Floorplates from a Conceptual Model
A slice can be thought of as a representation of a theoretical floor level. Slice floorplates provide a way to translate the
3D geometry of a mass group into something that can be used to generate the individual floors of a building. Slices
can be converted to space boundaries or polylines, and then to walls.
Slices and Mass Models
Like mass groups, slices are chosen and manipulated by an associated marker, the slice marker. When you attach mass
groups to the slice marker, the slice marker creates the perimeter geometry of the building, known as a floorplate.
Anytime you change the mass groups attached to the slice marker, the floorplate is updated.
If you attach mass elements instead of mass groups to the slice, the operational aspects (additive, subtractive, and
intersection) of the mass elements are not recognized by the slice. To have these aspects recorded by the slice, attach
the mass group. For more information about additive, subtractive, and intersection operations, see “
Creating a Mass
Group ” on page 627.
From Slice Floorplate to Walls
After you create floorplates, you can convert slices to space boundaries or polylines, and then generate walls. You cannot
create walls directly from a slice. The slice is simply a way to mark each floor level of the mass group.
Generating a Slice
Use this procedure to generate a slice. The slice object is defined by a small crossed box. Like the mass group marker,
the slice marker can be located in a convenient place in your drawing. For more information about the mass group
marker, see “
Creating a Mass Group ” on page 627.
You can create multiple slices at regular height intervals. A slice marker is created for each slice.
Generating slice objects
1 Open the tool palette that you want to use, and select a slice tool.
If necessary, scroll to display the tool that you want to use.
2 Specify the number of slices you want to create.
3 Specify the lower-left and upper-right corners for the slice marker.
TIP Keep the slice marker small so as not to clutter your drawing.
4 Specify a rotation for the slice marker.
5 Enter the starting height of the slice.
6 Enter the distance between slices, and press
ENTER
.
7 Press
ENTER
.
Specifying the Slice Elevation
Use this procedure to change the elevation of a slice.
1 Select the slice marker, right-click, and click Set Elevation.
2 Enter a new slice elevation.
