How to Split a Straight and Continuous Surface?
 

I have a continuous section of pipe in my model that I want to split into three surfaces for my mesh. I'm looking for finer control over the model so I can change the boundary conditions for different sections along this length. I normally just Split by Patch, but for this application I can't since the pipe of interest is just straight.

I've tried to use reference geometry to split up the 3D-CAD model, but to no avail. Any suggestions?

The next thing I'm looking to try are part curves, but I don't know how to generate them with any finesse yet.

Thank you for any input.

Hello.
To create a group of bodies from a starting body, you need to create slices or slices that will divide your tube into a new body.Attachment 99523

Move the desired part of the body and cut it down and return to the initial position. So you can divide endlessly.

This is a way of dividing the initial coordinate system by a plane. If you create several offset planes with a given interval, then you can divide without moving and returning back.

An example of dividing a pipe into new parts by offset planes.

This is exactly what I needed. Thank you so much!
