Thanks, Michael. Good thing is there are enough tools to achieve the desired result. I was also thinking of an auto kind of trimming when it comes to lines/curves to be used in bool/trim ops. Two intersecting lines, for example, offsetted on both sides, then the original lines disappears as well as unwanted lines such as those inside the intersection. I think Moi should have some kind of an embedded programming tool like Autolisp or something so that users can participate in adding some little tiny functionality even if only when it comes to 2d shapes.

Anyways, this is still a draft. As they say a journey begins with one step. It's not necessary for me to render it lifelike. What's important is knowing that the tools are there to achieve the bigger magical picture.
