Well here's another 'latest and greatest' 2008 option. Isometric dimensions. Not the fakey ones we did in the past. Honest to goodness true Iso dimensioning.
You place them like regular dimensions, but based on the points you pick, you can get the correct orientation on the page.
As always if you right click before you place the dimensions (when your still seeing the dimension preview), you can get additional options to use part workplanes to help 'adjust' the dimensions orientation.
I'm looking forward to finishing this side project so I can really use this feature!
