Beam Structures & Joint Control

I was hoping to be able to model a simple beam structure suchthat I could approximate member forces in gusset supports as wellas reaction forces of the ground connection.

I defined a custom profile of cross section and created structuralmembers along defined path which was devised for placement ofloading.

My main complaint is lack of control over beam joint location andneutral axis.

Am I missing something simple since I have used other codes whereit is possible to define wireframe sketch and assign I/A values tothe beam element.

Notice the two attached pictures with primary difference being thesketch used to define the path of structural elements.

Thanks for the help,
