Q - question

Applying STRETCH to 3D objects in AutoCAD.

A - answer The standard command STRETCH does not support 3D objects (solids) in DWG drawings. But you can use similar functionality in some other commands to "stretch" faces in 3D solids.

  • The command PRESSPULL allows to select one or multiple faces in a solid and pull/move them (individually along their normal vectors) into one or another direction.
  • The command SOLIDEDIT offers its option Face > Move which can be used to move faces specified by selection and edges.
  • The easiest method for moving individual faces in 3D objects are the grips (3D gizmos) displayed after selecting the faces with Ctrl+select resp. after subobject selection (Shift+F1 to Shift+F5).
  • The most similar method to the standard 2D stretch is the LISP utility 3DSTRETCH, downloadable from www.cadstudio.cz/download. Load it with APPLOAD and type the 3DSTRETCH command. Select the faces to be stretched by window selection and specify the displacement (by 2 points or by a displacement vector).
