A constraint-based sketcher addon created by hlorus for Blender that allows you to create precise 2d shapes by defining CAD geometric constraints like tangents, distances, angles, equal and more. These Sketches are then converted into beziers or mesh which still stay editable through a fully non-destructive workflow i.e, Geometry nodes and modifiers.

Please Note: This is addon is very much a work in progress and quite experimental thus don’t use it on production files without a backup.
