Coping steel beam to beam not showing

[davidedge]

Hi All,

I have a portal frame where two steel beams (call them A&B) come down to form a valley. There is also a steel beam (call it C) running between the portals at valley level. I want to notch A&B around C but although it appears to work at first it then goes back to showing the beam extension.

Attached below shows before and after notch, but on the second image once I un-highlight the beam on the right is when it goes back to showing the extension on the beam and no notch.

Any advice is gratefully received.

Thanks, Dave

Additionally I'm trying to change the haunch properties, is there a way to change them globally as I can only see a way to do them individually.

Hello

Could you upload model with these three elements. I cannot reproduce this problem on my example.

Thanks in advance.

Hi, Attached a reduced version of our model. The right hand beam is notched and when I change the length I see the notch then it disappears again. Ideally I'd like to have a clip connection but again I'm having trouble getting that to work correctly.

Thanks, Dave

Thanks.

Now, I can reproduce.

I see reason of this problem. These beams with defined coping have connections created on second ends. When connection is created, geometry of connected beam is exchanged to fabrication geometry. Unfortunately, beams with fabrication geometry don’t support coping.

So.

I see only one workaround. Remove coping and create cut on beams manually by using “Opening by Face”. Openings are supported by fabrication geometry.

Thanks for the info and understand.

I wonder is the any reason why I can't use the clip angle connection, I've tried the double clip angle too and get strange results.

Figured it out, I have the wrong primary member selected and I need to use the skewed clip angle, doing once side at a time.

Thanks for the help diagnosing my problem in the first place. Much appreciated.

Yes, in some cases default primary element is not perfectly set.
