You will get access to a ZIP file immediately after purchase.
If you purchase a CAD guitar plan, your ZIP file will include both a DWG and DXF file. You get both formats so you can decide which one you prefer to work with.
If you purchase a PDF guitar plan, your ZIP file will include one or more PDF files. You can print these on your own printer as a poster or take it to a print and copy service, like Kinko’s, and have the PDF printed on a Size E sheet.
