Hi everyone,
we created a lot of Step File for Sheet metal production using Rhino Common.
Our general approach was:
- extrude a Profile Curve as an Extrusion
- change it to a Brep
- select an Extrusion from the document
- change it to a Brep too
- cal the Boolean Difference from both.If we export this File as a STEP file, the cut in drill holes are not "real" holes, but made out of two Half Circles (red an cyan)
The Edge curve is not a circle, nor an ARCOther Software packages can't detect these holes to be drills - which raises the question.
How can we create "REAL" Round Holes and "Revolved" Holes through Rhino Common
Not sure if this example is actually better - but the edge curves are ARCs here. This was created by the "_roundHole" command. Still the edges are split though.
This is an Example of a STEP File created by Inventor:
It's one Surface and 3 Arc Edges (also not a circle)
Thanks
Martin
