Dean the viewport system works well for me. I can see the merits of the drafting palette but it doesn't work with the way I draw.
I have tried it and been disappointed when I couldn't change the drawing the way I wanted to. I ended up exploding the block which was a bad move because everything lost its associativity with the walls.
Torfinn my whole model would be a block. To edit it I would need to be in the block edit mode.
And there's nothing wrong with using both
Viewports and the Drafting Palette; using one doesn't necessarily exclude beneficially using the other.
Example: What if you, Nikki, had some elaborate timber-frame trusses in the house you are modeling and creating construction drawings of. Along with your normal Viewports, and perhaps some, Perspective View Viewports or something-- just for "eye candy" and referencing-- you could have a Block that is your timber-frame trusses, and you could use the Drafting Palette in Paperspace to detail to the craftsmen exactly how to build the trusses. For example.
Or what if you had a very custom cabinet that you wanted built exactly as you envision, complete with some very detailed interior shevling. Again, you could make that a Block, and insert the construction details in Paperspace via the Drafting Palette. With that cabinet in place in the middle of your house model somewhere, it would be tedious to get all the view and sectionals, etc. into Paperspace via Viewports... the Drafting Palette would work well for that type of construction detail as well.
It is my belief that one does not have to use either Viewports or the Drafting Palette exclusive of each other
in the same drawing; and in fact, a user could likely benefit from using both.
