Arch opening - line type bug

[RobiLMan]

Hi, I'm having problems with changing the line type of arch opening in Archicad 29, I even tried it on a fresh projekt on different version and it still didn't work, it seems like it is a bug. All i wanted to do is change the linetype of arc line to the same as the opening linetype...

I think the problems is that the arc is made from many lines and not from 1 curved line.

Any ideas?
