step to stl converter

[Skywarp]

Hello, but how to convert a .stl to .step using a script

[jg847]

I am also interested in doing this. I tried to do it using the GUI, but FreeCAD freezes during this process and I am unable to do so. Doing it via script would be much better.

I have found some of the utilities necessary in the process, such as

Code: Select all

mesh=Mesh.Mesh()
mesh.read("Pump.stl")
shape=Part.Shape()
shape.makeShapeFromMesh(mesh.Topology,0.05) # the second arg is the tolerance for sewing
shape.exportStep("Pump.step")

but I receive the message

The mesh data structure has some defects

in the terminal, and the process never finishes. I guess this is because the mesh is not waterproof and so I need to analyse it and make repairs (such as in the GUI tutorial
https://www.freecadweb.org/wiki/Import_from_STL_or_OBJ) but I cannot seem to find the script calls for these functions.

Any help is appreciated.
