I have a rough 2-D drawing of a simple mechanical part and now need it translated into a clean 3-D CAD model. The geometry is straightforward—mostly basic shapes—yet every stated dimension must be hit exactly, as the part will move straight to fabrication once approved. Key points • Source: one 2-D sketch (PDF/PNG) that I will supply immediately after kickoff. • Deliverable: watertight, print-ready .stl file (STEP or native file is a welcome bonus, but not required). • Detail level: keep the design true to the sketch without adding ornamental or intricate features. • Tolerances: treat all provided measurements as non-negotiable. I will provide critical dimensions and any allowable variance up front. I’m happy to clarify intent, answer questions quickly, and review early screenshots so you can lock dimensions before final export. Once the STL passes a simple mesh check and matches the drawing, the job is complete.
