I firmly believe upgrades aren't, tech support doesn't and help isn't. That being said.....I tried ACI Sketch for about 87 minutes, and decided I would rather give myself a root canal than try to understand it, so dropped $159.00 or whatever to get Apex BACK, it having handily disappeared with the UAD update. Don't go there. Question(s): When I tried to arrow up through a sketch the cursor stops at every cross line location, if you follow that. This I assume is an "added feature". You used to be able to arrow up from your keyboard and not fight your way up the sketch. Does that make sense? And yes I put in interior walls. I don't care if you've been appraising for 62 years and have never drawn an interior wall yet, I do. I find it rather enjoyable. Not as enjoyable as a weekend away with Katherine, my squeeze, but enjoyable in its own right. Any help anyone can give me. And yes, I always carry one of my Glocks if in a bad area. Come to think of it, I always carry a Glock, period.
