When you need DWG to PDF
DWG is the working format of AutoCAD and many compatible CAD systems. Architecture, construction, engineering, and production drawings are made in it. But the recipient does not always need an editable file. If a sheet needs to be shown, printed, approved, attached to a contract, or delivered to the site, PDF is usually more convenient.
Converting DWG to PDF turns a working drawing into a document for viewing. This removes the dependency on AutoCAD on the recipient's side and simplifies passing between designer, client, contractor, reviewer, and print shop.
What is preserved and what to check
In the PDF, sheets, viewports, lines, hatching, dimensions, text, blocks, title blocks, and general layout are typically transferred. But before sending, check fonts, scale, line weights, color, underlays, external references, and sheet format. For important sets it is worth comparing the result against the source DWG on several representative sheets.
For a CAD exchange format use DXF to PDF. If you need to move in the reverse direction from PDF to working geometry, see PDF to DWG and PDF to DXF.
Tasks this suits
DWG to PDF is useful for approval with the client, printing on a plotter, sending sets for review, passing sheets to a site foreman, and archiving approved versions. PDF is especially convenient where the drawing needs to be simply opened and used as a document, without editing the model.
The source DWG is best kept separately. PDF is convenient as the final layer for viewing and printing; all changes are best made in the working CAD file.
What is DWG to PDF conversion used for
Approving sheets
Send the client a PDF so they can open the drawing without AutoCAD and see the version for approval.
Printing on a plotter
Prepare AutoCAD sheets for output on paper in a format familiar to copy centers and print departments.
Delivery to the site
Create a PDF for a tablet, phone, or printout when the crew does not need the source DWG.
Project archive
Save a final copy of the drawing in PDF alongside the working DWG for storage and sharing.
Tips for converting DWG to PDF
Check fonts and dimensions
After conversion compare labels, dimension chains, and title blocks against the source AutoCAD sheet.
Verify sheets
For multi-sheet files make sure all needed layouts are in the PDF and in the correct order.
Assess print quality in advance
Check sheet format, line weights, and readability of small elements before sending to the plotter.
Keep the source DWG
PDF does not replace the working drawing. All further changes are best made in the master file.
