ok...so I'm not there yet - still at home packing up...but at some point today I will be in beautiful Hawaii. Tomorrow is another fun AUGI CAD Camp and a day of learning will be had by everyone (me too). I love attending the CAD Camp sessions as well - I always learn something!
AutoCAD Hip Tip on Reverting Back to your Previous Design:
So you're drawing along in AutoCAD and you realize you are not pleased with any of the design changes you've done. You could undo back to when you first opened the drawing, or you could use the cool Express Tool REVERT. This command will first prompt you to see if you do indeed want to abandon the changes you've made (just for insurance purposes), will close the file and then open it right back up again.
Think of it as shaking that Etch-a-Sketch! It's super speedy - so give it a try!
I'm off to the airport! (hope I didn't forget anything...oh yeah...sunscreen!)
