Use this procedure to add a ceiling grid with settings that you specify on the Properties palette. Spaces and closed polylines can be used as boundaries for ceiling grids.
- Open the tool palette that you want to use, and select a ceiling grid tool.
Alternatively, you can click
. 
- On the Properties palette, expand Basic, and expand General.
- Select a boundary:
If you want to… Then… place a ceiling grid within a space click Select object for Boundary, and select a space in the drawing. place a ceiling grid within a closed polyline click Select object for Boundary, and select a closed polyline in the drawing. - Expand Dimensions, and select No for Specify on screen.
- Specify the settings:
If you want to… Then… define the width of the grid enter a value for X - Width. define the depth of the grid enter a value for Y - Depth. lay out the grid with evenly spaced bays along the X direction expand X Axis, select Space evenly for Layout type, and enter a value for Number of bays. lay out the grid with a fixed bay size along the X direction expand X Axis, select Repeat for Layout type, and enter a value for Bay size. specify the offset distance from the start point along the X direction of the grid expand X Axis, and enter a value for Start offset. The offset distance may be used to reduce the effective grid size. specify the offset distance from the endpoint along the X direction of the grid expand X Axis, and enter a value for End offset. The offset distance may be used to reduce the effective grid size. lay out the grid with evenly spaced bays along the Y direction expand Y Axis, select Space evenly for Layout type, and enter a value for Number of bays. lay out the grid with a fixed bay size along the Y direction expand Y Axis, select Repeat for Layout type, and enter a value for Bay size. specify the offset distance from the start point along the Y direction of the grid expand Y Axis, and enter a value for Start offset. The offset distance may be used to reduce the effective grid size. specify the offset distance from the endpoint along the Y direction of the grid expand Y Axis, and enter a value for End offset. The offset distance may be used to reduce the effective grid size. Tip: After specifying the desired settings, you can move or hide the Properties palette to expose more of the drawing area. - In the drawing area, specify the insertion point of the ceiling grid.
- Specify the rotation angle of the grid, and press Enter.
- Continue adding ceiling grids, and press Enter.
