I am the founder of CADWOLF. I am not sure where that tagline comes from. CADWOLF will eventually be a full scale engineering solution. The idea is that an engineer designs the system mathematically in web pages on CADWOLF that we call documents. These web pages are then linked to a CAD system, a finite element model, and a part tree that links all of the components. By doing this, users can design engineering systems whose components adjust automatically with changing requirements. In other words, you change the load on a truss and the truss components update their thickness, material, etc. Right now, it has no CAD component. It has the initial step which is the web pages that act as documents to simultaneously solve and document engineering problems.

When I hear CAD I think, "Computer Aided Drafting", typically 3D solid modeling for Mechanical Engineers.

Same here, although I upvoted in the hopes that their definition of "CAD" could be extended to other markets. Curious if this is potentially competitive with other YC investments, namely Upverter[0] and CircuitLab[1], and how does that affect an Apply HN entry?
