I’m a structural engineer with 15 years of design experience, and for a long time I wanted a simple but genuinely useful tool for quick conceptual sketches: something that would cut a rapid structural check down to a few minutes. The software I used every day was powerful, but far too heavy for testing an idea early in a project. So I started building RodX for myself, as the tool I always wished existed. Because I’ve been on the user’s side for years, I know exactly what engineers need from this kind of software and what just gets in the way. Today’s web technologies made it possible for one engineer to turn that idea into a working product.
