Hello dear people!

  1. I would like to create a circular segment. How can I do that?
  2. I have a line in an arbitrary shape and would like to create a parallel line to it at a distance of 3mm. How can I do that?

Thank you in advance!

Normally you can use the offset function for this kind of thing, can you show your shape here with the desired segment?
