Intersecting plane against a curved surface comes out very jagged

Wanting to make a floor for my boat, I took a plane, made it a group, paced it in position and intersected with model. Every time I do this the lines in the plane come out very jagged. What am I doing wrong?




You’re butting heads with the facetted nature of the curved surfaces. You can’t get rid of that but you can minimize the appearance by using more segments in your curves.

Ah ok, so no way to intersect with the “smoothed” surface I guess.
Thanks for the reply.

The smoothed surface is an illusion created by blending the shading of faces across their joining edges. Nothing except the edges and faces actually exists!

So I’m asking for some magic then, take the real edge count, multiply it by (user inputed number) and give me a smooth curve edge.
I do some developing myself for iOS & Android, nothing is impossible!

Indeed, nothing is impossible except asking for something other than faces and edges. But perhaps more magic is needed than you realize.

You can see in your screenshot that the hull of your boat consists of triangles, which create a jagged boundary with the floor. There is no abstract smooth shape that these are derived from. So, the extension would have to figure out what you want from “smooth” based only on those edges and their vertices - perhaps something like a cubic bezier spline - generate new vertices to whatever resolution is needed to obtain smooth, and then completely regenerate the hull faces and edges (both above and below the floor) as well as the floor boundary to use the new edges. Possible yes, but not simple! A tremendous increase in model complexity could easily result.
