Adjusting Cutback

[lucis29]

Hi everybody,

I'm trying to cut 2 Steel channels (UPN120) at an angle of 45 deg. I'm trying to use Cuback, but it doesn't seem to work. I've made some tests and it seems that cutting at 45deg doesn't work when the profiles are rotate (at 90deg).

Question: Is there another way to cut the profiles?

Thank you.

Cutback isn't the tool for this. This is a manual override of the beam length / joint conditions.
You're either looking for the Cope command (Modify tab) or you can define a 45degr refplan and use Cut Geometry

Thanks Marjin.
The Cope doesn't work the way it should, but cut by a 45deg plan, yes.
It's time consuming, but at least it's a solution.

I know.... I wish they would fix the coping tool!
I believe Tools4Revit has an Addin which does a much better job at it. Don't know if you have to do this a lot but then it might be worth investigating.

I don't do this too often. Steel detailing is done in ASD. I use Revit only for concrete formwork and general steel plans.

if you are trying to miter the tow channel try to use opening by face..

[lucis29]

I'm not very familiar with opening by face. Can you please detail a little...

Thank you.

on the "home" tab select "opening by face" select a plane that is perpendicular to the direction you want to cut (in my example the vertical web)
Then just draw the shape of the void extrusion (cut out or offcut) you need.

Thank you Mark.
This is good for cutting the hole for the door.
The disadvantage for the 45deg cut is that it takes even more time then the Cut-by-plane. The advantage is that after the removing of the plane, the cut still remains.

Thank you all for the answers.
