Printing a brim

[peteruithoven]

For adhesion problems it would be interesting to print a raft. The obvious issue is time, printing a raft beneath the whole structure takes a long time. But what if we do something like a skirt but without distance, on the inside and outside.

There might be a start somewhere in here: http://stackoverflow.com/questions/1109536/an-algorithm-for-inflating-deflating-offsetting-buffering-polygons

@daid any tips for generating skirts?

Relevant: #92

In Cura, this is called a 'brim' [a skirt with distance 0 indeed]

I'm using Clipper to generate the offsets: http://www.angusj.com/delphi/clipper.php

Nice, OpenSCAD is implementing Clipper as well.

I found the JavaScript version: http://sourceforge.net/projects/jsclipper/ Demo: http://jsclipper.sourceforge.net/6.1.1.1/main_demo.html Downside, as usual is that it takes 97KB. In comparison, jQuery is 93KB and our own javascript code is 82KB. This is all minified.
