Is there any rotation in a truss?

If you are using a truss symbol: Right click on the symbol in the resource browser, edit the 2D portion. Make sure all the classes for the truss are turned on. Select all and delete. The symbol will change from being a hybrid symbol to a 3D symbol. You can now rotate it freely about any axis. hth. read more

The forces in trusses are given in nodes/joints unlike frames in which loads can be given anywhere like in joints or in member itself. And also the joints in trusses are made by a smooth friction less pins which doesn't take any moments so bo there way for trusses other tha to take either tension or compression forces. read more

A planar truss is one where all members and nodes lie within a two dimensional plane, while a space truss has members and nodes that extend into three dimensions. The top beams in a truss are called top chords and are typically in compression, the bottom beams are called bottom chords, and are typically in tension. read more

Rotate things on the bottom end of the truss rather than the top! That's one of those stupid-simple "why didn't I think of that" moments. It keeps any added weight (there should be very little) below the pivotal center of balance and that's a very good thing. read more
