Insert frame complication to assign to a line

[darnelle.stipp]

Hi all,

I am trying to draw a simple frame in inventor. I drew the line-frame, but when i try to assign a frame member like a i-beam to the lines, it doesn't allow me to click any line. I have watched a couple of tutorials online, and it seems like the difference is that my Input Geometry options are in red? might this be the reason> and how do I restore it to be able to assign a frame to a line.

thank you

Hi! Is the sketch an assembly sketch or a part sketch? You can pick points, an edge, or a 2D/3D sketch line in a part within the assembly. But, you cannot select a line in an assembly sketch.

Many thanks!
