Sorry, clicked submit before I finished the post, and I think I’m too new to edit.

Grasshopper to tween curves on a surface and offset them. Python to split up curves for the brick pattern, place alignment markers, model the stretchers and splines, etc. BowerBird to draw geodesics at the seat edges in order to guide the tweening and help the wood grain follow the piece curvature. 4-axis CAM in Python.

Veeery nice. Thank you for that we could see the whole process.

Hi @StephenT
Wonderful video! Thanks for explaining your process and the work involved.

This is great work! I love it when Grasshopper creations make it to reality and this is a beautiful example of persevering and solving problems until you got a result.
I would have given up with the assembly!
5 star review 
Nice project. Just showed up in my Youtube feed
Impressive! Any links to the CAM or is it a homemade sauce?
The end result is just impressive!
Wouldn’t there be an easier way to do this via tenons as bones? Butterflies joints or some flexible wood/joint cut/assembly?
Thanks! The CAM is home-brew. I’d like to get it in shape for release someday.
I’m always on the lookout for joinery ideas. Tenons, floating tenons, and splines are good options for CNC joinery, but here edge joints work well and are simpler. For rotary axis work, some joinery requires constraints I didn’t meet, like having the rotary axis vector of adjacent pieces be coplanar. I think a butterfly joint falls in that category.
