Place the section tool to create the slice. Right click on the slice to 'create group from slice'. Move off to the side some known distance (I usually use 1000"). Right click on the group, turn into component (so you can name it and save it to it's own drawing later). Edit the component - add dimensions, possibly fill in ends of timbers that you want to see solid, etc. etc.

Move back to the original location. To control visibility of this component use the Outliner and hide / unhide or you can create a layer for 'Bent1 Dims' or similar. Create a scene with everything you want to see aligned (you might want to use 'align with section' and turn perspective off in the camera).
