I have a set of electrical schematics that now need to be turned into production-ready drawings. The job calls for both 2D drafting and 3D modeling in AutoCAD: flat wiring diagrams that clearly label every symbol, conduit run, and termination, plus a companion 3D layout that shows how the components sit in space for enclosure and cable-routing checks. The level of finish I’m after is moderate—clean line weights, organised layers, accurate dimensions and call-outs, but not the ultra-dense fabrication detail you might see on shop drawings. Think installation-ready rather than photorealistic. To make it easy for us to iterate, I’ll provide the rough hand sketches, device lists, and reference photos. You return: • Editable DWG files for both the 2D schemat...

The electronics must be laid out in Altium Designer, and the firmware written for a PIC microcontroller—my platform of choice for this project. The unit will be installed in a dusty setting, so component selection, conformal-coating guidance, and protective routing practices should reflect that environmental challenge. I can share schematics of earlier prototypes as a starting point or we can work from a clean sheet if you prefer. Once the electrical design is firm, I’ll need you to develop and thoroughly comment the PIC firmware, then walk me through flashing and in-circuit debugging so I can maintain the codebase in MPLAB on my end.
