Sample files for use with AP203 applications are listed below. The images for the files were generated using the STEP Desktop Viewer

A few of these files are particularly useful for testing. The block.stp file has trivially simple geometry and is a good starter test. The as1_pe.stp file has a good example of a context dependent assembly structure, moon_buggy_asm shows mapped_item assembly structure, and rear.stp is a nicely complex, well filled-out file.

Most of these file contain advanced brep data (conformance class 6), but some contain faceted breps (class 5) and some contain surfaces or wireframes without any topology to bind them together (class 2)
