Handling Tessellated Shapes.

Post by keithsloan52 »

I developed the importer for the OpenSCAD workbench.

If a user imports a model with a hull request they can end up with a Tessellated shape, is this something the Path workbench can handle?

I do not know anything about OpenSCAD or hulls, but I tried opening your file and playing with the Path WB.

It is clearly possible to set up a Path Job and make paths of various sorts.

I am not sure what to do with a tessellated "hot dog", so I did not go any further.

Certainly worth testing by someone who knows what is wanted.

The one big issue I saw was that many Path operations require selection of faces or edges. There are a great many faces and edges in the provided file, so that selection could be tedious and difficult. Perhaps there is some simplified group selection that I do not know.

I tested 3D Surface for both Planer and Rotational Scan Type and there seems to be no problem when leaving the selection as whole geometry.
Only checked surfacing operations, but OCL is happy enough.
Presumably in working with hull you would only be looking at surface contours.

Thanks for the info - Think need to find somebody who is into OpenSCAD with access to CNC etc who can do some testing and report back on their experiences.
