I agree with Randy. Part of the reason for little explanation about dimensioning in paper space is due to the fact that there is very little to do to set up for it. Simply set dimassoc=2 and make sure your dimscale and dimlfac are = 1. Then start dimensioning! it does not matter at all what scale your viewports are set to, AutoCAD will take care of it.
I make new viewports, modify the model, copy viewports from one layout to another (use copyclip), and spend time much more productively than trying to calculate scales for annotation scaling. Isn't that what they did in the old days on paper? Isn't that how errors creep in too easily? Annotation scaling is just AutoDesk's way of making the folks happy who continue to be scared of paper space after all these years. I wish they would at least try just as hard to make us paperspace users happy.
Try dimensioning the different scale viewports in the attached dwg.
Rtprider, it is my opinion, however, that DIMASSOC=2 is still not yet stable enough to rely on with any certainty. We set DIMASSOC=1 and manipulate DIMLFAC by viewport. It's a little more effort, but our dims don't flake out on xref's or geometry without physical elements at defpoints (center of circle).
Had Autodesk spent just a little time fixing the instability of DIMASSOC=2, they could have foregone all the annotative gymnastics completely.
I didn't know dimassoc=2 had any bugs. I'll keep aware of it now. I wish they would keep the associativity to the solid model when I modify it instead of disassociating the dimensions.
Then there are the bugs I love to hate - 3D Hidden and 3D Wireframe viewstyles. To get past it I set my vieweports to only use 3D Hidden for plotting/printing. Works for me!
I consider it an issue that needs repair, when the dim loses it's associativity for any reason, including editing a solid, or an XREF, especially if they won't re-associate as sometimes occurs with XREF'd circular components. having to review each drawing prior to plotting severly restricts batch plotting.
Other than a sure way to cause problems, I haven't found a use for 3DWireframe
