Summary0002294: Some step files are not imported correctly
DescriptionI use freecad (quite succesfully) on my job, there we are a team of 3 designers. One uses Rhino, another uses Solid works and I'm using freecad, to share our work we use STEP as file format for exchange.

I had no problems for importing the STEPs porduced by solidworks, but odd things happens when importing the ones generated by rhino; models are loaded fine, but when I try to make a sketch on top of the imported object I'm unable to use the external geometry tool to import edges, on the terminal output I get:

Not yet supported geometry for external geometry
Failed to add external geometry: Not able to add external shape element


funny enough if I take that step file and I load it into solidworks to export it again in step the resulting step file will work as expected.
Steps To Reproduce1-Download the steps on the file.
2-import the rhino one in freecad
3-select a face and make a new sketch
4-Try to import edges withn the external geometry tool.
Additional InformationThis its been there from(atleast) 0.14 until the last daily build

The file named solid.step is the same step file loaded into solidworks and then exported again, that one works fine. The fcstd files are the result of importing both models into freecad.

No matter what you do; Saving as fscstd, make solid object,make simple copy, make a clone, use the shape generator, export step again with freecad, the 'wrongly' loaded model will not work with the external geometry tool.

The problem is that the edges of your rhino.stp object (at least the faces I looked at) are made of b-splines, which aren't supported yet by the sketcher.

Apparently SW does some good job at turning them into lines... Interesting...

I'm going to close this report, as a request for b-splines support in the sketcher is already there in issue 0002070
