Okay, had a chance to do a little more looking -
Emy pointed out the new space styles and features - much better, with more control over the space style and better data input should result in a more accurate analysis of the model. Better reports, too. And the more I use the ribbon, the more I like it - it just needs to be better organized.
The pipe library is finally starting to take a more realistic shape - better organization, but still needs more content - i.e. PVC only has socket type, lots of iron but no copper tube, so use the generic type. It'll work fine for now.
And it's amazing how little things can make such a big difference. In my class today on 2009, I was showing the round to rectangular transition - which in the current release looks like a reducer - but in 2010 it looks correct. The client will be happy - and Autodesk needs to include updates like this in a list when they present betas for review, instead of just putting out the highlights. We don't need a big powerpoint or fancy document - just leave us a trail of breadcrumbs to follow, we'll be good...
I'm hoping to actually get some documents written on customizing parametrics in both ACAD MEP and Revit MEP this year, already started on one as part of project for Autodesk. Watch this blog for updates...
More to follow - thanks!
