Hi,
During the geometry modelling of a pipe branch, three conical pipes need to be combined to create the pipe branch. the intersection surfaces inside the branch(as shown in the cutting view) need to be trimmed and the modelled should be combined to form one finite element object. Kindly could anyone assist me with how to perform this using object combinations or any other method? Tried different methods in object combination and failed. model attached

hi @eruchirapsl
you can model it in quarters using a background drawing from geometry imported in dxf or dwg.
The intersection of the cones can be done by straight line segments, certain parts could be compared to arcs.
You will also find here the means of cutting the arcs of a panel into several arcs of the same center and radius.
Best Regards
Thanks. By the way is there anyway of creating the model in Robot program itself?
hi @eruchirapsl
Yes surely. you can create lines or members. you can rotate them around an axis. for panels you can create them by selecting the contour points. Don't forget to adjust your units to ensure you stay within modeling tolerances.
Best Regards

Thanks. Yes. I did it in the same way(refer to my figure) by revolving polylines of three cones around three axes. But the challenge is trimming the FE surfaces which fall inside the pipe branch as indicated. In other words, the curve of intercept was the challenge. Anyway of using a boolean operation to do this?

I'm uncertain whether a Boolean operation on surfaces generated by revolution can provide an accurate solution in this scenario. While modeling point to point may be tedious, it's not overly time-consuming. If you frequently encounter tasks like this, investing in an in-house program might be worthwhile.
