I have been using Turbofloorplan3D Home and Landscape Pro version 12.
I have just downloaded a trial version of Version 15.
I see that it still does not show roof trusses. You can change the support from framing to truss, but "specify framing" shows only rafter options.
In Version 12, the view will show rafters when set to truss, but in Version 15 the view is blank unless set to rafters.
Is there any way of showing trusses in either version?
Roof tusses are not available yet in either version. This option has certainly bee requested many times, so hopefully it will come eventually. You can of course create your own using Members but much more time consuming of course. Once you have created one it is easy to export it as a 3DS and then import it into your catalogue for easy replication or use in future projects.
You will find it discussed in this post: http://forums.turbofloorplan.com/index.php/topic,1212.0.html (http://forums.turbofloorplan.com/index.php/topic,1212.0.html).
