To Subtract AEC Objects From 3D Freeform Spaces

Use this procedure to subtract a space or other AEC object from a 3D freeform space. You can subtract any AEC object that has a 3D geometry from a space.

Note: This procedure is valid for non-associative spaces only. If you perform it on an associative space, it will loose associativity after exiting the in-place edit mode.

1. Switch to a 3D isometric view.
2. Select the 3D freeform space from which you want to subtract an object.
3. Click Space tabModify panelEdit In Place.
4. Click Edit In Place tabModify panelBoolean drop-downSubtract.
5. Select the AEC object you want to subtract from the 3D freeform space, and press Enter.
6. Enter y (Yes) to erase the subtracted object, or n (No) to leave the object in the drawing.
