Convert 3 DWGs to STP

I have three straightforward mechanical part drawings in DWG format that Protolabs cannot accept. I need each one converted to a clean, watertight STP model that will upload without errors.

While you’re converting, please add any missing overall and critical feature dimensions as well as the material specifications shown on the title block; these details must carry through so the quote Protolabs generates reflects the correct machining requirements. The parts follow normal industry‐standard tolerances, so note the general tolerance block (ISO 2768–mK) in the STEP metadata or on an attached annotation view.

Deliverables
• One STP file per part, ready for direct upload to Protolabs
• A quick visual PDF or screenshot of each model showing the added dimensions and material call-outs for confirmation

I’ll supply the original DWGs immediately and can answer questions on geometry or materials the moment they arise. A fast turnaround is appreciated.
