Can any tell why if I bisect a circle with a straight line and then use the trim tool the whole circle disappears? It seems to be hit and miss, sometimes the circle disappears sometimes only half disappears which is what I want to happen.

Thanks Jim

Maybe, a surface that both intersects and lies outside the sphere could be used to trim the sphere into 2 hemispheres, of course deleting the par that you don't want.

I'm guessing that you have the line or circle at a different Z level or depending which plane you drew it. The program normally prompts you.

I started drawing everything from 2 points that were in the same plane. I think lines and circle are in the same plane. The reason I only want half a circle but most of the time when I try and draw an arc it doesn't want to lay flat on the plane it seems to be at an angle or upright.

Thanks Jim

Thanks Rockyroad

The snaps on the work plane did the trick

Yes above/behind the surface to intersect and cut.
