"Thanks for all the responses, I'll give it a try with a small piece. The overall is really big, started out with creating a Heightfield from Image & it was 1400x1200 points - with lots of detail, so I'll see how it goes.
"Mike as other said, depends on the desired precision. You could also use the patch command on the mesh wireframe to produce a NURBS patch. Also depends how "dirty" your mesh is and how close you have to stay to it. An alternative would be…"
"Hi Mike, I had the same challenge recently, the program you looking for is Geomagics it is a tool dealing with 3D scan data. It is very good at converting organic meshes to surface patches.
If you using scan data remember to reduce your point cloud…"
It has a tendency to freeze your computer if you are trying to convert a large mesh into NURBs. Also, the result may be a polysurface instead of one single surface. There are other ways to convert back to NRUBs (including a single…"
Does anyone know if there is a way to create a surface from a mesh? I know you can go the other way & create a mesh from a NURBS surface, but cannot find a way to go back. Anyone know either Grasshopper or Rh5?Cheers!See More
"This is kind of linked to a discussion I was having with Michael Freytag about a 20ga. steel assembly that I was working on. I have a condition where a "skylight can" of odd shape had to intersect a truss (not completely on…"
"Not only cool -- it would be extremely useful, because it would apply to all kinds of "bonded assemblies" and composite materials. We *are* working on it. It is going slower that we would like, partly because Rhino does…"
Is it possible to accommodate a construction/part with more than one material? I know currently one can only define a single material for a single solid, but what would it take to be able to define part of a solid as say wood, and the rest of the solid as say steel? Just would be very cool to be able to analyze this way as well.Cheers!-MikeSee More
