Steel Truss as a Structural Beam

Anonymous — Mon, 21 May 2018 15:06:30 GMT

Hi All

I'm trying to model a Truss as a Structural Beam. Problem is with the Diagonal Members.

As can be seen on the screen shot. The beam can be of variable length, with a variable number of diagonal members.

So far in the screen shot everything works fine. As the beam varies in length the diagonal members (which are a separate family) vary in width perfectly.

Trouble is when I array the diagonals I can add a parameter for the number of bays. Then when I try to change the beam length everything falls apart. I get a Constraints are nor satisfied message on the first diagonal, that was working properly before I applied the array.

Any help is very welcome. I've tried everything I can think of.
