hello, does anyone know how I can adjust the truss in revit? I opened the family and it's looking disconnected and fat... I tried pulling the diagonal bars but it won't move.

It's called 'Pratt Flat Truss'.
I tried editing the floating ends but they just won't move!
I tried selecting the individual bar but I can't seem to do anything to it; I tried edit family, but it looks fine there; I looked at the type parameter, tried changing the structural framing type, but there're only one option: ''Universal Beam:305x165x40UB'' Is there a way to change to another?
Actually the main thing I want is the truss to look like the little preview picture, and not have floating bits instead.

I am very new to revit so please excuse me, it's probably something very basic that I haven't learn yet.

This is a standard family with the program and the truss is fully controlled by parameters.
Look at the type and instance parameters. That is where you adjust this truss.

Yes it is. The problem is I don't know how to adjust it, it's looking fine apart from the diagonal and vertical lines aren't attached to each other... =(

Load the Pratt Flat Truss into your project and place it where you want it to be. Then you can click on the truss and select Edit Type in your properties and change the Top Chords, Vertical Webs, Diagonal Webs, Bottom Chords etc. If you know what members you want all of those to be and if they are not already loaded into the project you need to load them in before you can choose them. See thet attached pic for results.

sorry I don't know why the same reply has appeared twice. Thank you for all your replys. And thank you teafoe5 for the attached photo. It's exactly what I want to do, but could you tell me where I can find a member? It doesn't really matter, a metal one will do.

In your project on the Insert tab, select Load Family, then structural framing, Steel, W-Wide Flange, then choose the member you want. If you didn't want steel you could choose a different member.

Thank you so much! I have now successfully changed the structural framing type to ''Welded Wide Flange:WWF350x137'' however, the overall appearance is still looking strange.. I've attached an image. How can I make those ends join? and have I chosen a wrong member? Because it's looking fat and short...

The webs of the truss won't miter or look as nice as you want it to. If you are doing it for appearance reasons you can create your own structural truss family.
