mat c,
It appears you built this object in plan and then saved it as a GDL object.
Did you save from the plan as a door or as a general object ?
Did you save from the 3D window ?
You can tell by looking at the "sub-type" field at the top
of the parameter list.
If it says "General GDL Object" or something similar then it was
saved as a general object.
If it says something about being a door, which it apparently is because
it cuts holes in walls, then something is strange because doors and windows are modeled in the 3d script as lying flat on the X Y plane
and are tipped up when placed in a wall in the floor plan.
There are some strange rotations in the 3D script that I don't understand.
You may have to re-save the object you made in plan making sure
to save it as a door.
It might be possible to change the sub-type in the sub-type field
but I am not sure about this, in this particular case.
If it is a door then commenting out some of those strange rotations,
starting with ROT x, might fix the object.
