Hi ckerch

- DXF /DWG Importer Power Tool--> this Power Tool imports only 2D entities to be converted into Punch intelligent elements--> for example if you import a plan--> select a line--> convert to wall or staircase, etc. If you experience problems with this feature, please see my tutorial
http://www.punchhelpers.com/acadtutorial.html
- Doors and windows are Punch special objects and can't be imported. However, with the programs including the Door Designer / Window Designer Power Tools (as AS 5000 for example) you can develop your own models of doors / windows
- The ppv files are Punch PreView files and they are just the thumbnails for 3D objects, textures, etc--> see RB's tutorial to create PPV files
http://www.punchhelpers.com/rb_resources.html
- If you have a 3D file of the window--> you can import it in the 3D workshop--> follow my tutorial

(you must create the hole in the wall with an empty casement)
