Will you 3D print the result?

You should be in the pub more often (if it's possible )...

Have you tried TIGs 2D tools (2D line styles) for this?

You can easily find my newby posts. I spent my early days reading absorbing and learning as much as I could. [...] I followed and searched the forum questions until such time as I felt I could answer a question or two. Attempting to answer and reading the better answers taught me so much. So many excellent and patient users giving their time and knowledge freely. An amazing community. I thank you all.

Proxy on steroids...

Would be a nice one for the SubD example topic... http://sketchucation.com/forums/viewtopic.php?f=397%26amp;t=63826

You should download and install the Plugin Store from this forum, you'll find all of Fredos great plugins there...

Or something like the WireTool?

I wouldn't create gcode with SketchUp directly. You should export a solid object as STL and use an external slicer program (Cura, Slic3r, Makerbot, KISSlicer, ...).

You can move the top geometry (edges, faces, ...) with the move tool to the right (inside the group).

You know these?

I am looking forward to the next steps...

There are some plugins that can do this, one would be PointTool.
