Constraints on a Space Frame!

Hi,

I'm doing a crash simulation on a space frame and have problems with the constriants on the individual parts of the frame (actually all of them), what constraints am I supposed to use in Abaqus?

I'm used to work with ansys so I might have done some Abaqus beginner misstake...

...but the thing is that I've imported the geometry as a sketch from SW and thereafter added the beam profile on each "part" of the frame (btw if anyone knows how to do this without assigning a section assignment and orientation to each part seperatly, it would be great!!).

When I assambled all the parts I used an Independent Instance, this info might help.


I have also attached the project file (about 1 mb) bellow.

When I write constraints on the parts I mean ofc joints!
