Convert Duct Sketches to CAD

I have two hand-sketched ductwork layouts that now need to become clean, professionally drafted CAD drawings. Each drawing should be redrawn to 1 : 100 scale, include all the existing dimensions shown on the sketches, and present a clear, moderately detailed plan with readable measurements—but no extra engineering annotations beyond what is already provided.

When the redraft is complete, export each sheet to high-resolution PDF so I can print and share them immediately. If you prefer to work in DWG or DXF first that’s fine, as long as the final hand-off is a print-ready PDF.

I will supply scans of the sketches right after we start and will be on hand for any quick clarifications so we can keep things moving smoothly.
