are there some resources for learning how to use the mesh tool. the help menu is useless. i've created a hole as per the AC14 user tutorials, but unlike that tutorial i end up with a hole right through not just a depression. not a big deal, but i'de like to know why. also, i'm now trying to adjust the terrain but so far i'm only able to do it point by point. very slow. i recall in AC14 being able to select just one contour and moving it as a whole, now i'm only able to select the whole mesh at once. the links in the help menu don't do anything, so i can't open the PDF's or sites. must be another bug. also, when i've selected a point, the pet pallet opens and i must select the "elevate mesh point" tool each time. what a pain in the ass. each time the pallet opens the Z tool is selected, but as soon as i move it switches back to the move tool. this too must be a bug. thoughts on the guide?
