I'm creating a screen and I'm trying to sweep along a rail and for some reason grasshopper won't sweep along the rail with sweep one. Both inputs have vaild planar curves but once put into the sweep 1 there is no values being inherited into the sweep for some reason. Can anyone tell me why this is. I'm a new user so this may just be a simple fix but I'm not seeing it. I'm using wip 6.0059.
