I recently installed AutoCAD 2015 Mechanical on a new machine. When I use the IGESOUT command the proper translation window pops up as shown in picture #1. The dialog box does not show the options button where I can manipulate what layers are exported via IGES. I have attached a second attachment from AutoCAD mechanical 2014 showing the options button in the IGES translation window that I have previously used with success.
So in essence how would I be able to recover the options button in the IGES translation window in AutoCAD Mechanical 2015?
