split along existing lines

[arekm]

Hi.

I have a object:

https://myhub.autodesk360.com/ue297e4b5/g/shares/SHabee1QT1a327cf2b7a036938333f46ad3e

(check it to see what's under red line)

that I'm trying to split along existing sketch lines to split object into two parts. One part is marked with red (everything above red line)

on this ugly picture:

I saw tutorials that use additional lines/splines etc to make the cut but I guess it has to be possible somehow to use existing part of this for splitting?

I created a sketch of the Split lines you show in red and it worked fine.

So new lines are always needed (in my example) and you can't point to existing lines to do the split.

Ok, thanks.

Which way should the split go around the circle, and how can the split go around a circle from line to circle?  Wouldn't that have to be an arc to define the split?

Maybe like trim does - it is able to figure out intersection of line and circle for example. So clicking one chunk by one until whole split line is choosen.
