Thanks for the reply. I think I got it. At least partly. You place the tiny, tiny Infinite plane icon on the cut, select the solid and then click on the Infinite plane icon. Now I get a straight cut. But now I'm trying to use a curved plane. I've created curves (Beziers) and lines, used Cover surface to create a plane, but when I want to use this to cut the solid, it tells me 'Inconsistent face-body relationship'.

Did you intend to add a video? I don't see it, only double posts.

Thanks for that. It also reminded me that one can use a line on a solid to push/pull, I had forgotten about that. Why are you using two lines? If I use one line and put the Infinite plane icon on the line, somewhere, it does a straight cut as well.

Now I can do a straight cut, but what when it is curved?

I know how to do it with a solid, but I actually started asking the questions as I want to understand the cut with the plane. You can make way more advance cuts this way.

I didnt know you could, and just tried but it did not work. What am I doing wrong?

I created simple cube and drew a line across by snapping from one side to the other of the top face (as shown).

But when I hovered the Push-Pull tool over the top face, I was only able to select the whole face and not half and half. I must be doing something incorrectly..

I've got a video at masterviacad.com that does some splits that might be helpful.

Around the 2:50 timeline in the video I show splitting a complex solid into something that can be shelled using an infinite plane and extruded surface.

Actually now it seems to be working. I went to the Snaps tool box and was messing around with it. Now the Push Pull tool works on any line that I add to a solid face.
