I am wanting to export a STEP file of a six faced geometry from grasshopper without having to first bake into rhino then manually save as. This is because I want to create variations in the geometry and have them automatically export in one go. I require the faces to be named because the STEP files will be used in STAR for CFD. If they are named I can automate CFD analysis somewhat. The only file that maintains the face names I have found is STEP (I may be wrong).
I’ve used human to name the faces successfully, but to get the STEP file I have to first bake it to
Rhino, and then manually save it as a STEP.
I have managed to get the file exporting from grasshopper as other file types e.g. .x_t, but the face names aren’t preserved. For some reason when I use the same method to export a STEP the file is empty. Am I missing something?
I’ve included a simplified grasshopper script with a cube for the geometry.
Output STEP.gh (15.7 KB)
