I get the following error message when running code on a specific set of drawings (not all drawings). When I click OK, I am kicked complete out of AutoCAD and/or the VBA IDE. Title: AutoCAD Error-abort Msg: Error handler re-entered. Exiting now. My code is only trying to get a layer or create it if it does not exist. Something like: On Error Resume Next Dim objLayer As AcadLayer Set objLayer = ThisDrawing.Layers(strLayer) If ObjLayer Is Nothing then Set objLayer = ThisDrawing.Layers.Add(strLayer) End if As I mentioned, this problem is only happening with a certain crop of drawings that are nearly identical, so I would guess that something is probably just wacky with them (I have recovered & audited). Otherwise this utility works great. However, the brutality of the error and inability I have to track it down using regular debugging methods makes me curious as to what may be the exact cause. Has anyone else out there seen this before? Curious, Mark Sanchez
