sweep 2 problem

Hi, I have a problem with the sweep 2, when i connect the rails and the section curve the sweep 2 turns to grey in grasshopper, but in Rhino it doesnt appears. I have attached a Grasshopper definition, a Rhino file and a screen-shot of the form that i build in Rhino with the command "sweep 2" but when i want to do it in grasshopper it doesnt work.

Hi Pablo,

the Sweep functions that are in the Rhino SDK are not very good. The Sweep command is using more advanced fixing routines. We're currently rewriting functions like Sweep, Patch, BlendSrf, NetworkSrf as SDK functions so this should become available sometime in the future.

Hi David,
i see that sweep2 command in thino accept also points data, but in gh not.
In the rewriting this components are you improving also this?
thx

This is pretty much stopping me in my tracks at the moment. I'm trying to loft a wing with elliptical planform and anhedral, keeping the airfoil sections perpendicular to the rails. Seems like a pretty basic function to have it not working. Perhaps I am failing for other reasons, but I checked the direction of the rails etc.

Solution: I just went the other way and lofted the thing.

I am running into this same issue...

I baked my two rail curves [polyarcs from gh] and a line i created using the two end points of the two curves to use as the section curve to sweep around the 2 curves...

The sweep2 command works wonderfully in Rhino, but in GH it does not appear - thoughts?
