Hi, I am trying to connect edges of surfaces on the photo by folding them multiple times on different axis at certain angles of which I am not sure how to get. I want to basically join back unrolled surface. Please advise how I could achieve this. Sorry if I’m confusing, I don’t have enough knowledge to explain properly…
that would create nonmanifold edges, what are you going to do with these surfaces later? you can use NonmanifoldMerge but i am not sure if the edges getting together is your actual issue if so you could turn on solid points and use setpt to bring the edges together. if you have any problems you can also post the geometry or part of it.
Hi encephalon, thank you for your reply. I would like to add some thickness to the surfaces later but for now I just want to connect them together to make folded shape as you could imagine doing so with paper folding.
I tried to manually connect edges using rotate3d but I can’t find the right angles to align them together…

right: final “folding” - which is a rotation

the triangle have to rotate (_rotate3d) around the joined edge.
you can construct the required angle with two circles.
red and green axis as
_line Four Point
red and green circle as
_circle Around Curve
now you can
_rotate3d both triangles around the according axis, using intersection _IntersectionSnap
if their are more then three triangles / surfaces connected at one point, the (local) solution will not be unique.
hope this helps. if you need more help, please upload a .3dm file that illustrates the step you struggle with.
hope this helps, kind regards - tom
Thank you Tom_P, I will give it a go!
that s a setting where you do not have a unique solution.
just showing 2 of many…

mid front: first rotation
mid back: second rotation
