What is the latest best way to convert a mesh to surfaces?

[Mike_A]

Hi,
I model from scan data for a living,
I find working with pointclouds far easier than meshes in Rhino, I generally use CloudCompare (Free) to extract a pointcloud from the mesh, then work with that.
I use the following techiniques;

How to model properly with clipping planes and point clouds?

Hello, 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. Problem 1: when elements are cut by clipping planes, I can not select them nor snap to them. Problem 2: When I draw an element in one of the ortho views, it is created on the origin plane. When clipping planes are active - the object disappears. Then I have to find the object in one of the other view…

Selecting Points in a pointcloud with SelFence

Hi, This video shows my “Surface from pointcloud methodology” that I am trying to improve. [How to create a surface from a point cloud.] I am now trying extracting sections through a pointcloud using _CurveThroughPt + Selfence It works pretty well, but I would like to be able to reduce the thickness (width) of the fence to select a thinner slice of points in the pointcloud. At the moment I can only fudge this by zooming into the Fence curve when I execute the command. Mike

More recently, I have been using Rhino 7.0 to convert the input mesh to a Quad mesh, then convert that surface to SubD’s …it works beautifully.

Regards,
Mike.
