Hi everyone! first post here
I'm using simplify3d with a Prusa i3, which is my second printer after an up!mini. I'm still getting to know the software, so I activated the raft to test it with the following model: http://www.thingiverse.com/thing:430112. To my surprise, the raft covered a rectangle the size of the object, even though most of it doesn't support anything, which looks like a waste of time and material. The up! software generates rafts only in areas that actually support something, and so I think it would be a good improvement if the same could be done by simplify3d.
