This is a rather dull question as I am sure I am overlooking some simple solution, but I am at my witts end.
Perhaps someone will know.
The problem is that I have a curtain wall with circular reference line and I am unable to edit the endposts to be perpendicular to that reference line. Is there a solution? Thanks for any advice
(the endposts are set to the same element as the middle posts which are oriented correctly)

The Reference Line of the Curtain Wall may be an arc, but the Curtain Wall is always generated from linear segments that approximate that arc. You will notice that the Boundary Frames are always perpendicular to the Panels running into them.

If I had this situation I would probably create Profiles in the Profile Manager for both the left and right Boundary Frame, and I would use those Profiles in the "Profiled Frame 22" GDL Object for those Boundary Frames to achieve what I want.
I have not tried this , but in theory this could achieve the exact desired 2D and 3D representation.

Thanks Laszlo, that is the course I was going to take, however I was thinkiong that perhaps I am overlooking some simpler solution.

Using profiles is great in the CW tool, BUT, the coding is a bit numb if the profiles are anything other than rectangular, it simply takes the extremities of the profile shape and cuts back the connections to suit. I have resorted to using SEO's to trim my CW frames in situations where the ends need to be angled.

skawagon, What you think the fabricator will supply and is the discrepancy in the drawing worth the struggle to correct it in the model? I like accurate modelled drawings but sometimes you just have to accept the limits of the software, consider whether the "error" will be really visible in the output and possibly resort to 2D detailing for critical items.
