Creating a 3D Letter, Curves are not closed, where is my error?

[Draxl_Andreas]

Hello,

I have anywhere some trouble, i can`t close the loop. how can i create a polycurve?
Where is the missing node or even a geometry-error?

Hello @Draxl_Andreas
Have you tried PolyCurve.ByJoinedCurves ?

[Draxl_Andreas]

hmmmm…

I think i have no overlapping lines or even dublicated
Can i say something like “unique Items”…?

I believe your individual curves need to be in order. If they cross or form multiple closed loops the node will fail.

I tried it with a simpler form. So it creates the surface but not the extrusion
is it list - deepth problem, how can i create the extrusion?

GroupByKey is for grouping items in a list. It’s not going to do what you want and you’re providing a single item anyway. You’re getting errors because you’re trying to pull index 1 from a list that only has one item. You seem to already have the PolyCurve so you should be able to patch and extrude that as is.

hmmm… or need i just one polycurve > surface > extrusion
?

I got it!
