Vectorization (Raster to Vector) and Convert to 3D Solid (.stp)

I am looking for someone with experience in Vectorization (Raster to Vector) and Convert to 3D Solid (.stp).

The 3 drawings attached should become 3 seperate .stp files for use of waterjetting. The material we are waterjetting is 3 mm thick.

Key Requirements for Waterjet Cutting

⚠️ Critical Checkpoints for CNC/Waterjet Geometry:

Closed Loops Only: The machine needs to know exactly what is "inside" (scrap) and "outside" (the part). An open path will cause a machine error.

Scale: Ensure your vector file is scaled to the exact real-world dimensions (in mm) you want the final pieces to be before exporting to STEP.

Lead-ins/Lead-outs: The waterjet pierces the material with a high-pressure blast before moving along the cut line. Your fabricator's CAM software will handle this, but keeping sharp corners perfectly clean in your CAD file helps optimize the entry paths.
