Summary0033543: Data Exchange, Step import - STEP file is not imported correctly
DescriptionI have a model built in Eyeshot ( and I can export STEP files or IGS. It seems that the STEP file (attached) is not translated correctly by OpenCASCADE, instead the IGS file is opened correctly. I don't know if this is a bug or a limitation. I'm not using OpenCASCADE directly but I am using gmsh which uses OCCT to import step files.
