As we from Autodesk often heard, that a lot of users are struggling to apply a pattern across several surfaces, my colleague @Andrzej_Samsonowicz and I worked on a solution for this. This script here is “work in progress”, and far from finished, but probably already helpful for the described task:
Multi-Surface-Patterning-2.20.dyn (265.6 KB)
You also need this .dyf file to be placed next to the script above:
ReorderCurves.dyf (6.3 KB)
Feel free to report bugs and enhancement requests here. A video demonstrating the use of the script can be found here:
Looking forward to your feedback!
