SOFTWARE RETURN POLICY Tinkerware offers the CAD 3.1 manual as a download, we have several screen shots to show the main windows and also will respond to email and phone calls to get more information for customers to have an adequate opportunity to assess the value of program prior to purchase.

Unlike physical goods, electronically distributed software and software licenses can be duplicated. Once our software has been delivered, it is unfortunately not possible for us to recall all copies. Therefore, Tinkerware does not accept returns, exchanges or provide refunds for products purchased. All sales are final.

We do not sell or ship overseas.
