point cloud IGES import

Altair Forum User

Hi,

 

I have a set of points in matlab that form the surface of a bladder and I want to import it to Hypermesh to mesh it. I export it from matlab as a IGES file, but when I imoprt in Hypermesh it does not show anything. I have tried importing a simple nurbs surface in IGES format into Hypermesh and it recognizes it. Do I have to make the points a Nurbs surface in order to import it to Hypermesh. I know I can use a CAD software, like SolidWorks, to make a geometry from the points but it is too expensive. Any help is greatly appreciated.

You can try it by creating a point in Hypermesh, export a IGES File and import it into a new session, looks like this:
