Lofting and Network Surf via Script / Rhino.Common

I’m at a point where I have 90% of a fan blade part automated with Rhino Python Script. I’m wondering what it would take to automate creating the geometry that bridges between the blade and the root. It looks like I need to delve into Rhino.Common, which looks like it might take a while to learn. Any ideas on how to solve this one?

I’d like to match tangency where possible between the two parts. When I do this manually, I split the main blade part so that I’ve got edges that are compatible between the two sections that I’m trying to blend between. I then use a combination of loft and network surfs. (Ideas on improving basic modeling also appreciated).

Ideas? I’m wondering if it’s possible to put points on edges and then select edges near the points? (Edge selection is needed to use tangency matching features).

Hi @brodiej,

What Rhino command did you use to fill in the bridge?

Sorry for long delay. I used Loft, selecting surface edges.
