Lattice frame with angle beam (L sections).

J_Marc

I am trying to model a lattice frame with angle beam chords. I am trying to replicate what's on the sketch. I cannot change the orientation and need some help please. I have attached my test.liml file. Can you provide the steps to achieve this?

J_Marc, is this what you are looking for (click on link below)?

Disregard previous YouTube link and see the one below (something wrong with the previous upload).

J_Marc, the attachment seems to have been lost.

If you mean rotating the L beams about their length axis, then you can do that with Element properties -> Orientation. It's a bit tricky with L because you're specifying the direction of the principal axis, which isn't aligned nicely with the geometry. The material properties box shows the angle of the principal axis relative to one of the flanges, so you can use that to calculate rotation angles.

I know that's all a bit vague, but not quite sure of the problem.

Thanks guys, the youtube video is a nice touch.
