This program copies a selected object to be extruded and places it onto a layer called profile and then extrudes the original so the user always has a backup of the extrusion in wireframe.
The name was changed from Extrude_Plus.lsp to aext.lsp for installing into support folder. Similarly the command to execute it was cchanged from EXT to AEXT so the Extrude alias Ext was not being used.
The justification for its inclusion is it's excellent lay out, error handling tacked on in one discreet section, the fact that it is the only thing I have adderessing layers and management and it is 3D drawing related. Consider preserving profiles for some sort of Autocad mid-plane extrusion routine or just having then if you want to do them from the profiles again in MDT or Inventor.
extrude_plus.lsp (Download) Command was ext but was changed to aext to avoid conflict with the Extrusion alias Ext.
