Mark,
I downloaded the exploded view.
Don't know if this is how you usually do it or if this is just a quick sample.
Anyway. Your exploded view only has one group in it... which is the vertical post. If you aren't already using all groups...I think you would find it so very much faster to do your joinery and to explode the drawings if the individual pieces are individual groups. Just my .02.
One of the first drawings I did was one "without" a lot of groups. Its a nightmare to go back to it now and look at it compared to the ease and accuracy we get now. In fact aside from using it for a visual drawing/elevation I doubt its even functional as a frame drawing any longer.
BTW why do you leave the gap on top of your brace tenons going down into your mortises? Just curious..
