DaxCAD was and still is a Mechanical CAD Package used by a handful of companies throughout the world in the late ‘80s and early ‘90s. It is still in use by a manufacturing company in the UK. It’s origin stems from Paisley College of Technology, now known as Paisley University.
It was written to be able to be an inexpensive, simple to use CAD application for a range of industries. As it happens it was sold to just a about all sectors from government to finance.
In fact General Accident insurance used DaxCAD to design all of their regional offices. DaxCAD was integrated by RACAL as their circuit board designer and by Advent as their vector mapping tool (English Heritage). All in all, not a bad pedigree.
