Demo page – Van Niekerk Engineering

On this page various design demonstrations are shown of analysis & design methods as well as 2D & 3D CAD and database modeling.
With an exception, code demonstrations are not shown, but implementations are possible using C, C++, Python, Perl and more.
For reasons of NDA, previous work for customers is not shown. If you have any questions about possiblities, please send us an email.
