How to model properly with clipping planes and point clouds?

[wim (Wim Dekeyser)]

Hi -

@s.urbanski

I have a problem while working with point clouds and clipping planes. There are three things that combined make me think that Rhino is useless for CAD modelling from the point cloud.

We don’t necessarily disagree. The following post is still very much valid:

Pointclouds in Rhino 6

Hi @subs, Can you please tell me specifically the URL of the links you found that are outdated? I agree with you that it’s important to get rid of (or clearly mark as obsolete) information that is obsolete. As for reverse engineering, Rhino 6 is not particularly good at it. However, now that you have Rhino 6, you can use the Rhino 7 WIP, and check out the Quad Remeshing tools - they’re incredible (if you can get from a point cloud to a mesh - that step we still don’t do well). There’s a workfl…

In the meanwhile, the https://www.food4rhino.com/app/cockroach plug-in was released that could help generating a mesh from the point cloud.

There are Rhino users that regularly model from point clouds - an example:

@rhettone Welcme to the Rhino forum. It looks like you are new to Rhino and possibly new to modeling with NURBS. The first step in reverse engineering an object is to learn to create models of smilar shapes. The User’ Guide, Level 1 Training manual and Level 2 Training manual are good places to start. https://www.rhino3d.com/tutorials/ Google NURBS to find out more about NURBS curves and surfaces. These are a fundamental building block for Rhino. If you want to learn more about how the math …

For less organic shapes, you’d probably want to create sections from the mesh and planes and use these sections to build new surfaces.
