simple perplexing door threshold

[domer1322]

I'm frustrated that I can't figure out this simple problem. In the attached image, the upper door doesn't show the wall lines as if it has a threshold. The bottom door shows the threshold (or ceiling) lines. I've been all over the door settings, with emphasis on the class and threshold settings, but still can't find why they are different. I understood that turning the ceiling classes on/off could affect this, but it doesn't seem to be working here. Both doors are inserted plug in objects. Someone please enlighten me.

One thing you could try... Make an exact dupe of the the one you like, then insert it into the wall and change only those settings that are required (e.g.: from Swing Simple to Double Acting). In my quick test, the Ceiling-Main Class turns on/off the wall lines.

Oh, and one more thing: make sure both Doors are inserted in the wall!

Is the object you're having trouble with something carried over from a previous version?

I've had this problem and found recreating the object from scratch sometimes works.

Dave, can you post a file containing that wall and the objects in it.
