Hey there, imagine this:
Bezier bases guides. Can be anything from a straight line to a complicated closed curve. With an option for "parallel" (for open curves) and "concentric" (for closed curves).
Without this option checked, the brush just snaps to the guide as it is. When it is checked, You can draw anywhere, and the brush follows with the chosen offset. If Your guide is a line, You can draw parallel lines. If it is a curve, You get parallel curves. If the shape is an ellipse, or circle, You can draw concentric circles or ellipses. You get the idea
Such bezier guides could be their own layers, or attached to an already existing layer or group.
For e.g. precise mechanical shapes this would be a great addition.
Wht do You think?
