Adobe. Make It an Experience.Anonymous commented
I completely agree with the above comment as well. Smart guides were working for me up until I installed Illustrator 2018. I had to reinstall the previous version because I couldn't find a solution. I had thought to reset the preference file but just gave up out of frustration. The "unsmart" guides were causing a complete work stoppage for me and were starting to cost me money because it prevented me from getting projects completely in a timely manner. This needs to be fixed. It's too bad that Adobe swallowed up FreeHand, I loved that program.
