Description | I am testing our NIST STEP to X3D translator that is based on OCCT 7.6.0 with very large STEP files. The largest STEP file that I have is about 1.5 GB. It takes about 30-40 minutes to process in CAD Assistant and our software. However, in two other free viewers (C3D Viewer, eDrawings Viewer) it only takes about 5 minutes. Is there something to be improved to reduce the processing time? I think the slow part is actually reading the STEP file.
