Detailed Mechanical Schematic CAD Drafting

I need to modify an existing 2-D CAD drawing of a mechanical schematic, finished to a “detailed with dimensions” level. The job is strictly schematic—no architectural or electrical elements involved—so every line, symbol, and call-out must align with accepted mechanical drafting conventions.

The source information I will supply includes hand sketches, component lists, and key measurements. Your task is to translate that material into a clean CAD file that can slot straight into our manufacturing documentation. Dimensioning must be complete and logically placed; hidden lines, centerlines, and section indicators should follow standard layer conventions for easy editing.

Preferred output: DWG (AutoCAD) or an equivalent format that opens flawlessly in AutoCAD 2019. PDF export for quick reference is required.

Acceptance criteria
• All components represented accurately in plan view.
• Dimensions match the provided measurements to the millimetre.
• Layers organized and named for fast future edits.
• File passes a straightforward audit—opening without errors, printing to scale, and reflecting the supplied sketches one-to-one.

Once the first draft is ready, I’ll review and return any mark-ups, and we’ll iterate until it meets the above points.
