Trim/Brep truncated cone

OK.

The trim is OK, but this is not the same thing…

please check this:

Curve middle line

Hi, I need to make something like this: [image] But not limited to a fixed distance between lines (offset)… So, I need to infill a area of closed line and divide the area to create X number of lines like the image, and create something like a “sin” [sinus] Any idea ? Similar to this (this shape is perfect, but is limited to offset): [image] similar post

I neet to make a simulation of 3D printer extruder

Width of extruder is the offset of central line (sin) (to simulate the width of extruder) and in the next line I need the inverse of the line (like a mirror)

So, you can check in the image the mirror of lines and the simulation of width (offeset left and right to de central line)

I’m trying to understand how to make this in your code.
