Hello all,
I am a newbie with a background in computer science but little if any engineering knowledge but am eager to learn. I am currently writing a Java program to visualize STEP files as an exercise. The Java part I get, the STEP File format, however, is another issue.
I am up to the ADVANCED_BREP_SHAPE_REPRESENTATION Entities and am having some issues regarding the transformations of the geometries. Within the ADVANCED_BREP_SHAPE_REPRESENTATION Entity there is a MANIFOLD_SOLID_BREP (which I can render as a series of polygons) however, there is also an AXIS2_PLACEMENT_3D Entity (or more than 1). How does the AXIS2_PLACEMENT_3D Entity relate to the MANIFOLD_SOLID_BREP?
Any help/hints (pseudo-code would be great) would be much appreciated.
Thank you.
