Hi Max,

I'm kind of unsure about putting what's really a geometry generation tool inside of the View panel.

Please keep in mind that both of those tools have been extensively worked on by developers whose main jobs are just doing those tasks.

There are a couple of different ways you can generate a section line already, you can draw in a line like you've shown there and then use Construct > Curve > Project to project the line onto the object, the result will be a section line:






Another way is to make a plane for where you want the section and then use Construct > Curve > Isect to generate intersection curves between the plane and your object.
