truss Automatic truss modelling advice/help

[Hobbiest]

Apologies if this has been beaten to death but I cannot find a solution on the forums and I just can't find an automatic way of fixing this issue.  I'm using X16 and modelling parallel chord trusses, as soon as the truss is over a wall where the room on the opposite side has a lower ceiling height, the truss seems to ignore the top plate and extends the seat of the truss lower (at the adjacent ceiling height) or doesn't cut at all.  Looking for advice, is this a sunk cost fallacy and I should just lock a working truss to copy over these zones or is there a setting I'm missing that accomplishes it?  The attached plan has a few different methods I tried without success.

I forgot to note that the orientations of the side rooms are not like in the plan example I supplied.  In the plan I'm working on, the side rooms come off on a 10 deg skew and are not perpendicular.  The angle is drawn on the exterior sides of the walls creating a courtyard.

I've run into this a few times and I always just end up building a truss in an area where it works, lock the truss envelope and copy the truss as needed to get the point across in the plans. Or sometimes even make a separate temp square building the size I want and lock the envelope on that truss and copy it to the actual building. Parallel chord trusses seem to be especially fussy.

 

Where I am the truss company will end up doing detailed shop drawings anyway so I don't usually try to get my truss details down to the knat's ass level of detail, but more refinement of Chief's truss building functions would be much appreciated.

I’m curious, who is ever going to look at your truss drawings and actually use it to build or even install a truss?
 

I realize some remote places don’t always have the benefit of a local truss manufacturer.  
 

As the Minnesotan mentioned, usually your truss company will have you approve their drawings and those drawings will accompany the delivery which any carpenter is already accustomed to reading. 

 

Are you just curious or are you going to manufacture those yourself. (cause I know some people do)

Thanks for the reply, I figured that was going to be the answer to my question....just lock and copy.

Short answer, this is my own house I'm currently designing.  Yes, I will get truss drawings from the manufacturer, but to keep the model as close to "real" as possible, I will still want to model the truss per their design, but now I know I will need to manipulate the truss after the fact.  Was just making sure that I wasn't missing something that let me keep it accurate OOTB.

 

Let me know if you want the long answer lol.
