The Floors and Ceilings toolbox contains six Architectural discipline tools. These tools are designed to increase productivity and offer the following features.

• The Place Floor and Place Ceiling tools place parametric solid forms. Thickness of the floor and ceiling forms can be set. The forms also allow for holes needed to place vertical shafts, stairs and other related design elements and conditions.
• When a space is identified for ceiling grid placement, the DataGroup height property for the space is used to control the elevation. When a non-space perimeter is used to create a ceiling grid, the elevation of the elements in the perimeter (the walls for example) are used to place the ceiling.
• An elevation setting is also available with the ceiling and fixture placement tools to set the placement elevation to the active floor reference plane/ACS as defined by the Floor Manager.
• Ceiling grid perimeters are associated. If the perimeter changes, the ceiling automatically regenerates. If the ceiling perimeter is defined by a space that was created by flood, the ceiling regenerates when the bounding walls (perimeter elements/forms) of the space change.
• Ceiling fixtures can be cells or compound cells. When a cell is used, the first shape in the cell definition controls the clipping boundary. When a compound cell is used, the first perforator controls the clipping boundary.
• When the active model is a 2D model, fixtures are placed as conventional cells rather than compound cells and the 2D cell footprints are used for drawing purposes.
• When ceilings are replaced, the active color weight and style symbology is automatically set to match the target ceiling.
• After ceiling grids are in place, they can be extruded to create 3D forms. Do this using the Extrude Linear Element to Form tool.
