Attaching Clipping Profiles To Ceiling Grids - Autodesk 24108-051400-9000 - AutoCAD Revit Architecture Suite 2008 User Manual

Changing the Position of Ceiling Grid Lines by Editing Grid Bays
Use this procedure to reposition grid lines by editing the number and spacing of grid bays using the Bays worksheet.
1 Double-click the ceiling grid where you want to move lines.
2 On the Properties palette, expand Dimensions.
3 Edit grid bays:
If you want to
edit grid bays along the X axis
edit grid bays along the Y axis
The Bays worksheet lists all bays on the selected axis, their distance from the start point of the grid, and
the spacing of each bay.
4 To change a bay, click one of its measuring values in the list, and edit the value.
5 Click OK.
The line positions have changed according to your settings.

Attaching Clipping Profiles to Ceiling Grids

You can attach a clipping profile to define a mask around a ceiling grid or to make a hole in a ceiling grid. You could,
for example, create a mask to define a ceiling grid for an irregularly shaped room, or exclude parts of a room from the
ceiling grid.
For a mask, you can use closed polylines and spaces. For more information, see
Boundary" on page 1515.
NOTE To attach a clipping profile, you must first draw a closed polyline or space with the desired boundary or hole shape.
Masking Ceiling Grids
Use this procedure to mask a ceiling grid. A mask is a polyline shape or space that defines the boundaries of a ceiling
grid. Those parts of the grid outside the boundary are not displayed.
1 Draw a closed polyline with the boundary or hole shape you want.
2 Select the grid you want to mask.
3 On the Properties palette, expand General.
4 Choose Select object for Boundary.
5 Select the closed polyline or space you want to use as a mask.
6 Right-click, and click Deselect All to turn off the grid grips.
The parts of the ceiling grid that are outside the masking polyline or space are no longer displayed.
TIP If you want to restore the original grid shape, select None for Boundary on the Properties palette.
Creating Holes in Ceiling Grids
Use this procedure to create a hole in an existing ceiling grid. The hole is created from a closed polyline or AEC object
placed within the boundaries of the grid. Any parts of the grid inside the hole are not displayed.
1 If it does not already exist within the boundaries of the grid, draw a closed polyline in the shape of the
desired hole.
2 Select the grid, right-click, and click Clip.
3 Enter a (Add Hole), and press
4 Select the grid again, and press
5 Select a closed polyline or AEC object for the hole.
