Some of the 3D creation tools in AutoCAD 2007 use existing geometry to produce new 3D solids or surfaces. The default behavior in AutoCAD is to delete that defining geometry after the 3D operation has been completed. For example, if you sweep a profile along a path or revolve a profile around an axis, the original profile geometry will be deleted. In some cases, you may want to reuse that profile geometry for subsequent commands. If so, you can change AutoCAD’s default behavior so that it always retains the original geometry.
- Right-click in the drawing window.
- From the right-click menu, choose Options.
- In the Options dialog box, choose the 3D Modeling tab.
- Under “Deletion Control while creating 3D objects”, select “Retain Defining Geometry” from the drop-down list. You might find one of the other options even more approriate for your particular situation.
- Choose OK to close the options dialog box.
