Can anyone tell me how to create this type of truss?  Attachment 1 is the SP version of the view my engineer is requesting to see.  However the framing itself needs to look like attachment 2 with a horizontal top cord that I can add lateral and diagonal bracing to.

I'm still using 2016, so I don't know if 2018 has truss configurations beyond Fink, Howe, King .....

 

Obviously 2016 doesn't have a Piggy Back Truss, ..

 

Graphically in 3D, .. you can add (and tweak) beams to approximate the piggy back assembly,

.. in an Engineering sense, it doesn't pass real world configuration for a given context.

 

That being said, .. don't most truss suppliers provide the engineer worthy drawings for their product? 

 

I've never had to create this type of modeling for engineer approval.

Like Doug, I wouldn't have expected you to be trying to provide that level of detail, as that is the responsibility of whoever is providing the trusses.

I'm with you Douglas. My truss supplier provides section files for all the trusses in a package along with 3d views if I request. I let them take care of it.

Thanks everyone...this exercise is for illustration purposes only.  The engineer has all the truss specs, but wants to give the builder a color coded visual of the lateral and diagonal bracing.  Douglas has me pointed in the direction I want to go, I'm just not sure how to get there.  I seem to be struggling with adding beams in 3D and wouldn't  have a clue how  to get the bracing in...off to the HELP section to see if I can figure it out.  I've been away from SP for awhile and seem to have forgotten more then I thought I knew.

One approach might be to create the trusses yourself, each as a symbol, .. bottom truss as one, top truss as another.

 

.. or for that matter, .. one symbol that includes both

 

If you search posts by Keith Almond*, you should find techniques on creating 3D solids from your line drawings, ..

 

These truss symbols can then be positioned vertically relative to each other and block copied to suit your truss spacing, ..

 

As far as beams in 3D, .. the ones I tossed in were re-defined to suit 2x4 dimensional and elevated into place via the 'common' tab when editing the beam

If you search all 3000 you might be here a while ... Try this one http://softplan.com/...er-roof/?p=8039

To put the bracing in, use custom sized beams ... you can angle them to suit almost any situation.

Keith, I managed to create the 3d truss I need but can't seem to get past step 5 in your tutorial. I can't find SYSTEM LIBRARY under SYSTEM OPTIONS (attachment).  Am I looking in the wrong place?  I've expanded everything I could find under SYSTEM OPTIONS... I just don't see the System Library.  Your instructions are pretty clear, what am I missing?

You have to be in the drawing window menu,  not the 3D window.

Thanks
