I have a structure made up of HSS Round shapes of varios sizes (5" to 16") and I have instances where one pipe size terminates into another, and in section it shows the pipe penetrating into the bigger pipe, when I need it to show as if the smaller pipe is cut and welded to the outside of the bigger pipe, or the the smaller pipe is cut by the bigger. Revit Structure doesn't seem to allow me to cut one pipe with another, it will only allow me to cut a pipe with a plane or level. Is there any way to make this happen?

Attached is an image showing one instance where I need it to show differently. We can't have the fabricator cutting a hole in the pipe and stubbing the other through then welding it.

Thanks for any help!

I figured out a way to do it, however, it only works on straight pipes, not curved. Attached is an image to demonstrate. I created a section/view paralell with the straight pipe that showed the outside of the pipe then used Opening By Face, which cut the pipe "somewhat close" to where I needed it. This is not perfect because it did not follow the curvature of the pipe it's connecting to, but good enough to show up somewhat correctly.

On the curved pipe below you can see it is not cut properly, but I have hidden (invisible) the pipe end line using "linework". If I did not need/want the set to be shaded then I could have used a masking region, but not a 3d solution. The opening by face does not seem to work on a curved pipe, so I have not found a solution for those yet.

I'll try to update this if I find anything else that works, more ideas are very much welcome!

Void family to cut the geometry of beams will also work. Please see the attachment. Tried with straight HSS beams.

Hopefully should work with slanted/curved beams also.

Good luck.
