Your CAD drawings and pdf's on the blockchain. Fast, cheap, easy!
CAD stands for Computer Aided Design
A CAD drawing is a detail image file format for displaying the components of an engineering or electrical design. The most common industry formats are .dwg, .dxf, and .pdf.
By saving your CAD drawings to the blockchain you are saving them to an immutable ledger to share with other or recall them whenever you need them. You control the privacy settings on anything you save to the blockchain, so you can make your files public by default, or private so you can share with only those you wish to view them.
