Working on new shapes. I did add at the model level the following shapes: Sphere, Circle, Boolean Operations (Cut, Fuse and Common). Also I've look forward to make other shapes: polyline, inifinite line, circle click on center, arc, spline.
Polyline and spline needs a design change as they need multiple dependencies. I did not finish this yet.
After I will implement them I will make them accessible from interface. So stay tuned!
