I’m working to unroll this 3D surface, make a 2D pattern (blue) and map it back to the 3D. However when I unroll it with the untrimmed 3D surface and map the 3D trimmed srf edges (black), the mapping is not quite the same as when it is unrolled the trimmed srf by itself (red). I feel like I’m missing something stupidly obvious… but been banging my head against the wall for too long - pls help!

Use ShapeMap. No need to install Nautilus, it is just for pattern making.

I’ll check up on these - looking to understand where those two lines come from/how they’re related - the intro video makes them appear somewhat arbitrary?
I have been trying to understand what exactly the two lines do for quite a bit of time but couldn’t. Maybe @jessesn can tell you.
The Line 0 and Line 1 are used to locate the positional relationship between a 3D object and its flattened curves, similar to the Base Line and Target Line in the Flow command in Rhino. For more information on the basic usage and workflow of ShapeMap, pls refer to the content below
