Jon, I was considering the implication of copper pours being multilayer. I like the idea, and my current implementation allows that as a future step..
In a copper pour the filled region is defined as a set of points. I assume that such an idea would require that each layer gets its own set of points, and as such would require a lot more work. Baby steps :) On Tue, Sep 26, 2017 at 12:07 AM, Jon Evans <[email protected]> wrote: > Nice job Oliver.
