Welcome

We have made this site as mobile-friendly as possible. Currently we find that for PCs and tablets, it works best on FireFox.

ProfessorCad has usefull apps and info for everyone.

Apps (Windows Desktop and Mobile Phone) are born out of customer requests and in-house requirements.

The variety is maybe a bit unusual, but each one is useful - you might find something you didn't know you needed!

For App Inventor Users we have palatable amounts of need-to-know information presented as tips, tricks and snippets.
We also offer add-on components for your Apps and PC Desktop tools to enhance your App Inventor productivity.

ProfessorCad provides a Bespoke Software Service too.
Let us know your requirements, we are trusted to respect non-disclosure agreements.

The ProfessorCad Website was established circa 2006. Why the wierd name, "ProfessorCad"? In the 1980s, the Internet was not as ubiquitous as it is now. However, I was able to join a Computer Aided Design interest group on 'CompuServe' and a similar group on 'AOL' (America On Line). As a pioneer using CAD in the Aircraft industry, I found I could help others with tips and tricks for practically any CAD system at that time. One day, someone crowned me 'ProfessorCad' for the help I gave - and then everyone followed suit.
