a very basic question. I am learning to import a STEP file and export it to STL. I modified Laszlo's code from https://github.com/lvk88/OccTutorial/blob/master/OtherExamples/runners/convertStepToStl.cpp
int main(int argc, char *argv)
TopoDS_Shape stepShape = reader.OneShape();
However, when I run
./main valve203.STEP out.stl
(the valve file was posted here some time ago and is also attached), the result is more or less empty; it says only:
solid shape, STL ascii file, created with Open CASCADE Technology
What's wrong? Certainly I am missing something very basic.
