A great addition to the user interface in SOLIDWORKS 2020 is the new animated tooltips that appear when you hover your cursor over some tools. This new functionality provides a quick overview of how a command works for new users, or if it’s one that you don’t use very often.
However, for some users, it’s quite possible that they wouldn’t want the very large, animated tooltip popping over their toolbar. In which case, the tooltip options can be controlled by going to Tools > Customize. There are 3 tooltip options, Large tooltips with images (new for 2020), Large tooltips without images (the default in previous versions) and Small tooltips. If you want to completely disable the tooltips, uncheck Show tooltips.
