Today we made a 1.6.1 alpha build to offer users some preview on the latest features we plan to launch.
We made a big rewrite on NaroCAD and added: integrated a solver algorithm, implemented the Sketch concept and 2D tools that use the Sketch, reimplemented Extrude to work with sketch shapes, added 2D dragging handles that work on the current sketch. A final updater version was also included in this build.
A sample movie that demonstrates lines drawn having a perpendicular constraint on them. Demonstrates solver behavior when a point is dragged:
Another sample that demonstrates drawing a rectangle (that is built from lines with constraints) and also a circle center connected to one rectangle corner:
