I have added door and window builder to my libraries but it seems to be causing some annoyances. It seems to have its own "door.txt and window.xtx" that are giving me a bit of grief. Every time I open a new project which includes this library I need to point to the .txt files that are part of the door and window builder package. However the worst part is that if I import drawings into plotmaker (or update drawings that were imported prior to using the library) I get a dialog box asking for me to open something with no indication of what it wants me to open. I have pointed to these same .txt file and it seems to solve the problem. Has anyone else had these type of problems with door and Window builder? I have emailed theometric twice with no response, but I understand the company is currently changing hands which is likely delaying any advice. These issues makes door and window builder virtually un-usable at this time. Thanks for any advice someone might have.
