Hi Karen.
I generate timber frame shop drawings with Layout quite extensively.
What follows is my work flow; which I have developed with a bunch of trial and error.
The key move is to make a separate SU file for each part of your system; great room, Master Bedroom, etc.
I use this new file for my Layout work.
I isolate each part of the frame that I want to dimension and I move them around in model space until I can dimension them and place them in Layout without seeing any extraneous members.
I do all of my dimensioning in SU, particularly with timber frames because you have so many instances where faces aren't flush and you have to rotate the model to get the point you need, which is a royal pain in Layout.
Once I have my new SU file, with everything dimensioned, then I can insert it into Layout and then navigate, in each viewport, to the view I want.
I don't use scenes in SU, though this would make things easier, becaue I experience a weird and annoying glitch with SU where, when I hit my middle mouse button to navigate, it jumps to a scene. This makes it impossible for me to "work" a model with scenes, so I have figured out work arounds.
So, the new SU file, when complete, is a mess of dimensions, and pieces all over the place, but everything far enough apart from each other to not interfere with my views in Layout. In your particular case, I would isolate the bent and dimension (at scale), I would isolate each timber in the bent, and give dimensions (not to scale as I display timbers isometrically), and I would have a scale plan view, with necessary walls, etc.
Hope this helps.
