Hello, I am pretty new to Rhino. I mainly use Grasshopper and make drawings with Rhino 6 and am looking to try some new functions. I have two 3D scans and a few questions. What is the best way to merge the outer curves and clean them up? Also, should I turn these curves into a surface before flattening them? I am wanting final result to be the stretched out template of the 3D scan so when the vinyl gets printed it will conform to the edges. Any help or links to content for me to study is highly appreciated
