Hi guys!
I am using Rhino standard version without any plug ins and Grasshopper.
I am trying to create a mesh from points clouds e57 file generated from Cloud Compare. I’ve read multiple tutorials but seems that Grasshopper does not recognise point clouds as regular points and delauney command does not work.
The point cloud file has 11 mln points.
Would really appreciate your help!
Hi Diora - ShrinkWrap is new in Rhino 8 and I can only find expired Rhino 7 evaluation licenses in your account, so that might not be available to you.
Since Cloud Compare is involved here, you might as well create the mesh in that application and import that into Rhino?
-wim
Yes, unfortunately the function is not available for me… But I did try creating a mesh in another software and importing it to Rhino. From there I used command meshtonurb but the result is too heavy and not manageable. Maybe there are other ways to work with mesh in Rhino in a more efficient way.
I am trying to produce a 3d Model of the object to be modifiable and openable in BIM programs like Revit and Archicad. I cannot use BIM program directly because the shape is too irregular. I hope this helps
Are you trying to create a mesh or is the end goal to create a NURBS model based on the mesh? If it’s a mesh you need, why not use the imported one? If it’s NURBS you are after, it’s going to take either a lot of surfacing skills or using the QuadRemesh/SubD/ToNurbs work flow suggested by @Helvetosaur - which is available in V7. It’s not a single command, but will quite quickly create a surface model from mesh input. Here’s a few videos on QuadRemesh for you to get started. So basically the idea is to Quadremesh the mesh to get a cleaner, more organized mesh, convert that mesh to Sub-D (can be done either as part of the QuadRemesh command or using the ToSubD command and then convert the Sub-D to NURBS using ToNURBS

Edit: OK, so it’s for BIM, so probably mesh. I’d look at Quadremesh in order to clean up and simplify the point cloud to a level of detail you can use.
