ACADuser Posted January 24, 2018 Share Posted January 24, 2018 Plan attached I'm having trouble with the truss base & building a truss over it. I built the trusses for the existing roof & need to show new trusses so I added a Truss Base. But the trusses will not build over the truss base. Any advice would be appreciated.

Alaskan_Son Posted January 24, 2018 Share Posted January 24, 2018 Eric is correct, truss bases are only designed to separate trusses that are running perpendicular to each other. I wish it worked for parallel trusses though. I think the best solution is manually modifying those overbuilt truss profiles. Link to comment Share on other sites More sharing options...
ACADuser Posted January 24, 2018 Author Share Posted January 24, 2018 Eric, I have used it successfully that way. Just thought it would work in any direction. Oh well, manually built it is. I'm going to add a feature request. Thanks Link to comment Share on other sites More sharing options...
Chopsaw Posted January 24, 2018 Share Posted January 24, 2018 I have done parallel trusses before in a piggy back situation but it required a temporary ceiling plane to retain the auto built trusses. Not sure I have time for the plan file today but I think it could be done. Link to comment Share on other sites More sharing options...
ACADuser Posted January 24, 2018 Author Share Posted January 24, 2018 I thought the Truss Base was the ceiling plane. Are you saying use a Ceiling plane in place of the truss base? Link to comment Share on other sites More sharing options...

Funny, I was actually just thinking that might be a possible solution and was planning on testing it out when I got back to the office. It seems that it may only work if you at least temporarily remove one of the roof planes or put it onto a different floor. Link to comment Share on other sites More sharing options...
Chopsaw Posted January 24, 2018 Share Posted January 24, 2018 Yes in the same position that the truss base would normally be used and you may have to lock the lower trusses and pull the ceiling plane in and out as you work with the upper and lower roof structures by Transforming and Replicating it into the back yard.

DRAWZILLA Posted January 24, 2018 Share Posted January 24, 2018 There is a bug in the system that trusses will not build over other framing, been there a long time but not sure if that's your problem 1 Link to comment Share on other sites More sharing options...

I’m really hoping they get this sorted before final X10 release. 1 Link to comment Share on other sites More sharing options...
ACADuser Posted January 24, 2018 Author Share Posted January 24, 2018 I did not realize or forgot (more likely) that you can edit the truss profile in a Section view by dragging the envelope of the truss once selected. In plan view you still need to drag the ends of the truss into position, lock truss & M-copy. That did what I needed. 1 Link to comment Share on other sites More sharing options...
Alaskan_Son Posted January 25, 2018 Share Posted January 25, 2018 Just tested out the extra ceiling plane method and that DOES work. Its a little tricky though as you have to lock your original trusses (no special snapping and lock truss envelope), draw the ceiling plane, and temporarily change your ceiling settings. Not a bad method though. Could be faster than modifying the truss profiles depending on how complicated the roof is and how many truss profiles you have to deal with.
