Thanks for the advice.
I’ll look at all possibilities but I have some work to do to just learn this technology. The truss plugin shows what is possible and I think any engineering calculations can be solved by using ‘codes’ that keeps the parameters within a range of values. Similarly to how plumbing codes allow the design of drain-waste-vent systems without complex calculations. I have never tried to program 3D applications before and this is very interesting.
I completed a 6 month object-oriented programming certificate a few years ago so I have an idea of what is involved (design patterns etc.) but it will be a few months before I have anything to show.
