In order to cut multiple tubes at a single node, use the "Element contour - Exact cross section" command.
We need to:
- Align the tubes with their system axes meeting at a single node.
- Select the tubes in pairs. First, use the command on Tube 1 and on Tube 2. Then, use it on Tube 2 and Tube 1, to obtain a symmetrical cut between the two tubes.
- Repeat for all the tube pairs. This example contains 5 tubes and requires 10 cuts in order to avoid collisions between the tubes.
