I have three reference images that depict mechanical assemblies and must be rebuilt as true 3-D models inside AutoCAD. Each drawing must show the full geometry of every component and part that appears in the pictures—no placeholders or simple extrusions—so exploded or section views read correctly later. You will receive: • High-resolution JPEG/PDF snapshots of each diagram, annotated with overall dimensions, callouts, and a notes layer that clarifies hidden features. • My short naming convention for layers, blocks, and viewports so file navigation stays consistent across all three DWGs. Deliverables (one ZIP on completion): 1. Three separate DWG files, one per diagram, each saved in AutoCAD 2018 format or earlier. 2. Any external references, textures, or custom linetypes packaged with relative paths intact. 3. A quick screen-grab of each model in isometric to confirm visuals before hand-off. Acceptance criteria: • Every component present in the reference is modeled, dimensionally faithful, and placed in 3-D space. • Objects are organised on logical layers with descriptive names (e.g., shafts, fasteners, housings). • Files open natively in AutoCAD without missing fonts, proxies, or binding errors. • No stray geometry, duplicate lines, or exploded texts. Once the three DWGs pass a brief cross-check on my side, the project is done. If a tweak is needed, I’ll point to the exact element so you can update and resubmit the file—no rework on entire models. That’s the full scope; feel free to propose a fair timeline and ask any clarifying questions as soon as you’ve reviewed the sample images.
