Create full-length UDLs

Full-length uniformly distributed loads (UDLs) can be applied to all one-dimensional member types (with the exception of braces and truss internals) as follows:

Open an appropriate view and set the view regime to Structural View.
In the Loading list, select an appropriate loadcase.
On the Load tab, click Full UDL.
In the Properties window, adjust the load details according to your needs.
To apply the load, click anywhere along the member.
