Is it possible to export my lattice mesh structure as a STEP or IGES file?

Hi everyone,

I am trying to save this gyroid structure as a STEP or IGES file, however each time I get an error saying that the STEP and IGES file don’t support meshes. Is there any way to get around this problem?

Any support is much appreciated!

Best,
Dylan

You will need to convert to nurbs. Most optimal would be to go mesh > subD > nurbs from the lowest res version of the mesh using Rhino 7 WIP. Otherwise you could convert direct mesh to nurbs but it going to be a lot of nurbs faces to keep the look of the curvature.

Why do you need STEP or IGES? Those are usually for milling manufacturing. 3D print should be STL or OBJ typically.

Thank you Michael,

I need a STEP or IGES file because I want to be able to modify the part in CATIA after the export from GH. I don’t believe you can modify an exported stl file in CATIA.
I will try this methodology asap, and I will let you know how it goes!

If you can modify something is not up the data format, but the type of geometry you are passing in. An mesh cannot be used to do surface operations, no matter if you are using Catia or Rhino. Create surface models and you are able to export and modify them in Catia.

Okay that makes sense, thank you Tom. I will have to keep this in mind the next time I am creating models in GH and modifying them in Catia.

Best,

Dylan
