Orson, Wayne,
I would agree. Please find attached a patch that implements "offset"

Subject: [PATCH] CHANGE file format for 3D model offset
- Reverts behaviour of 3e71ed2421f5df433c11a554e0756f6898e25b06
- 3D model offset now explicitly written in mm, using "offset" tag
- Any read "at" tag is converted from inches to mm
- This will not break any 3D model offset when reading files
- It will however render files incompatible with old versions
