Masking, combining and/or filling shapes

[maxmcd]

I'm trying to construct a dodecagon from arcs. Is it possible to combine shapes or fill areas created by multiple overlapping shapes?

eg: I wanted to fill in the area between the black arcs in this diagram to create a shape that looks a little like a 4-petaled flower.

From what I can tell...you'd have to find a way to draw shapes that fill up the target area or paint around it to make the shape you want. The petals in your example can be made of a combination of 3 arcs and 1 triangle.

You can find the Lain code here: https://gist.github.com/blad/e014ad6cf48de4ad9aa8e98475660184

It's more complex than I'd like.

Using Dotgrid or an SVG program then importing the SVG into Ronin might yield better results and readable code.
