Hi, I started Martin's "Edges to Rubies" tutorial prior to last summer. It seems like an excellent tutorial, but I stopped using it (and SketchUp) for the past 6 months due to other time commitments. I've waited so long to restart, that I think that I'll need to start over again to get my bearings. One initial directive that I was unable to resolve the first time that I started Martin's tutorial (and I'd like to get it right this time) is "How to Create a Working Directory". Martin suggests naming it C:\carrige_house -and that seems fine, but I'm not sure how I create this (file?). I have windows vista. I've tried Google, but that doesn't seem to bring up what I'm looking for. Any help will be greatly appreciated. Thanks, Zach
