RhinoInsideRevit : Create Structural Beam based on curve

Hi All, I drew a line in Revit and wish to loft a UB using the line as a reference.

When I try to view the element in Revit, this error pops out, any idea why?

I checked the V/G settings and everything is turned on.

Hi Jia,

Not able to replicate this condition, we’ll need more info to be able to help. Thanks
