I have a set of detailed 2-D drawings that now need to become clean, parametric 3-D models in Siemens NX. The parts are strictly mechanical—no surfaces or sculpted plastic—and I only require the level of fidelity suitable for functional prototypes. That means accurate dimensions, correct hole patterns, proper thread callouts, and clear feature trees, but we can leave out final fillets or production-specific tolerances. Your task is to open each drawing, interpret the geometry, and build an associative model in NX so I can iterate quickly before committing to manufacturing. I’ll supply the PDFs and any clarification you need; you return the native .prt files along with STEP exports. If you regularly work in NX and are comfortable translating detailed prints into solid, editable models, this should be straightforward.
