PDF Architectural Plans to AutoCAD

I have a set of design drawings supplied only as PDFs. The bulk of them are architectural sheets, though a handful of the mechanical pages carry simple 3-D views. I need every page rebuilt in AutoCAD so that the final DWG files mirror the originals line-for-line. Scope of work • Trace or redraw all geometry with proper line weights, layers and linetypes that make sense for architectural production. • Re-create every dimension, note, keynote and symbol exactly as shown so the files are fully editable. • Where 3-D call-outs appear on the mechanical sheets, model or extrude just enough to preserve the intent—flat faces and basic volumes are fine; no photorealistic rendering required. • Keep sheet numbers, title blocks and paper space layouts intact so I can plot straight from AutoCAD. Deliverables • One DWG per sheet, plus a compiled sheet set if you prefer. • Any custom fonts, plot styles or external references you introduce. • A short log listing any assumptions or clarifications made during conversion. Acceptance criteria The DWG prints must match the PDFs at 100 % scale, with layers organized logically and all annotations remaining live text. If you have questions about specific symbols or the small 3-D portions, let me know early so we keep revisions to a minimum.
