Welcome to our programming site. There's an introduction to customizing Visual CADD using the API (Applications Programming Interface), and then specific instructions for each language --and finally the tutorials where you get a chance to get your hands dirty. We've also included a section discussing the merits of a particular programming language, and a page of links to sites of interest for the programmer.

The examples are written for version 4 of Microsoft Visual Basic and Visual C++. We've also got brand new tutorials on API programming with Delphi!

Our hope is that you'll share your programming experience with others, so that we all can learn how to make Visual CADD work in exactly the way we each need. Send tips, code, and anything else via e-mail, and it'll be posted on the site.
