AutoCAD 2D Machine Parts Drafting

I need precise 2-D drawings of several machine parts prepared in AutoCAD. The goal is to capture every critical dimension, tolerance, and annotation required for manufacturing while adhering strictly to ISO standards. All geometry must be laid out on clean, well-named layers, and dimensions should follow ISO conventions for line weights, arrowheads, and text height.

Please work directly in native DWG format so that I can modify the files later if needed. A plotted PDF of each sheet will also be required for quick review.

Deliverables (all items are mandatory):
• Native AutoCAD DWG files for each part
• Matching PDF plots at full scale
• A brief layer legend and any custom ISO dimension styles used

I will supply hand sketches and reference photos as soon as the project begins, along with material notes and any critical fits. Drawings should be production-ready and error-free on first submission; a single revision round is anticipated to address minor comments.
