As in drawing a plane, And extruding it up to make a floor for example?.
I know there’s the grease pencil. But Blender seems to not put enough focus on that and when you draw something, Convert to Bezier, Convert to Mesh, And extrude it doesn’t come out right.
Also. I think a pen tool would be cool too. Instead of having to extrude a vertice(s) and spin them.
