This is a unique routine from Jay Thomas that draws trim around windows in AutoCAD. This routine includes a dialog box (DCL file) and a slide library (SLB file), so either unzip all the files into a location that is included in your support file search path or unzip these files to a new directory and add that location to your support file search path. Then you can load the LISP file and run the command WTR. The first time you run it, an options dialog appears where you can set various trim options. Subsequent executions of the routine skip the dialog, but you can always access it from the Command line prompts of this routine. Jay has also included a drawing file containing windows for easy sampling of this routine. Very nice.
