Creating and exporting surface from points

Specific domains Graphics and plotting

Dear,
can you please confirm my short summary:

  • there is a file that contains coordinates of a point cloud
  • The goal for you is to create a surface out of these points in step or IGES format.
  • The surface shall be further processed with a CAD software (e.g.: CATIA, SolidWorks, Fusion360, etc.)

Beside the very interesting topic for Scilab to perform this taks (thank you Stéphane for the code)

Creating surfaces out of point clouds … there should be existing software to do this…e.g.: Meshlab, CloudCompare, open3D.

Did you have a look on these?

Best Regards,
Philipp

Dear,

If you have a STL-file you can use Fusion360

  • import the STL-file and generate a surface from the mesh
  • export the surface as iges or step

tutorials via youtube…e.g.: Convert STL mesh to a Solid Body In Just 3 Minute | Fusion 360 #fusion360 - YouTube

If this is a one-time-task you could be fine with a 30day free licene from fusion360.
Of course…registration and stuff…but maybe a way to go. (?)

Good luck,
Philipp

Hi Philip
In the code I generated a matrix of points due to some calculation.
Normally I export this data in a file of curves.then import in creo and so on.
Now with NX it is not so easy work in the same way so I was searching a way to export from scilab directly a 3d file
thanks
Sergio

Hello Philipp
you are right,

In another way I could have the points of diferent curves and I would like to write that curves in one iges file
thanks
