algorithmic modeling for Rhino

This is a definition (WIP, attached) which creates sections for a laser cutter from opened or closed single geometry.  This won't work on every geometry, but it will work for a lot of them.  It uses offsets and booleans so it may be difficult to predict.

 

I'm also playing with a way to minimize material area for cutting (with galapagos).  If anyone can offer help to improve it, let me know! 

 

Update:

 

- Some issues with outside sections were fixed by culling perimeter members.

- Section cuts are oriented relative to one another with a cheap standard deviation technique.

- Galapagos optimizer no longer allows sections to intersect.

- Galapagos optimizer now coordinates y and x movement to minimize cutting area of material.

 

The galapagos run will be crazy in the beginning (will take a lot of area), but should look right after ten minutes or so.

 

For more on the galapagos run, see this post: http://www.grasshopper3d.com/profiles/blogs/laser-material-optimizer
