Nice. Constraint solving like that has been a feature in CAD programs for years. Here's Autodesk Inventor's 2D sketch mode.[1] You get an error if you try to overconstrain something. There's a symbolic solver checking for over-constraint. Under-constraint is harder to deal with. There's a count of the number of additional constraints needed to specify the drawing fully. You don't have to get that count down to 0, but if you aren't just sketching for illustration, it's expected that you reach the fully constrained and dimensioned state before cutting metal. Scaling problems dominate as drawings get more complex. It's easy to do this for high school geometry problems. It's hard to do it for jet engines. User interface design for dense drawings is really hard. What do you do when stuff is on top of other stuff? The big, expensive CAD systems (Autodesk, Dassault, SolidWorks) have struggled through the scaling problem. | ||
