Thanks for the blueprint, I've been struggling to get any of these to work with 2m foundations (They just don't align like the 1m versions do) . Any tips / tricks on how to make them in the blueprint designer would be greatly appreciated :)

Its a matter of position and orientation in the blueprint designer. It autocreates the blueprint outline in a way that lets it snap correctly to other foundations. For getting two pieces like this to connect, i've found that only 5° angles work. I've also found that using a single foundation in the center of the designer but at the desired angle produces the same effect. I've been posting comments about this on recent curve tutorials on youtube but I might also upload some blueprints of them just to let people know.

How do you get these to be chainable? I'm trying to create a 10 degree curve but they don't chain right.
