Intersection of a 3D shape with a 2D shape, resulting line isn't connected to the surface

Hi Sketchup community,

I’ve just got Pro on trial; I’m trying do exactly as the title, how do I intersect so that the cylinder can be “cross-sectioned” at the intersection line?

Everything was in the same context when I intersected.


Share the .skp file so we can see exactly what you’re working with.

Without the skp we can only guess. My guess would be that even if everything was in the same context, that context wasn’t open for edit when you did the intersect with. Results of intersect with always go in the open context.
