Panels for geodesic structure - 3pts to plane?
« on: May 03, 2017, 09:56:55 AM »
I'm working on my second script which is for cutting out panels for geodesic structures.

I need the tool (currently just the flange) orientation to change when cutting out the panels to provide beveled edges at the correct angle.

If I extend the corner lines to a 'focus' then orienting the tool tip toward that should work, but how to do it? Or should I be using one polygon as guide curve, and the other as a cut curve?

An approach using the toolpath utilities 'Orient plane' or '3pts to plane' would seem to provide a way ahead but I have so far failed to figure out how to use them...

Thanks in advance for any help.

Hello,

That's how I would solve it. Just take the control points of each of the polygons and use the "connection" between the edges as the tool axis vector.
Note that I've positioned it flat on the ground and I've switched it around so that the larger polygon is up. Otherwise the wrist of the robot could touch the material.

Best,
Johannes

Thanks again Johannes,
That's got me started...
