The ease of use with this program compared to other programs I have used previously was very helpful when trying out new features that were not available before using it as well! It took me some time getting familiar but once you do get comfortable everything seems easy enough from there onwards - no problems so far!! Not much at all really; just try different things until they make sense (or don't) then move forward :) Have been able to create complex parts without any issues thusfar which has helped my workflow tremendously especially considering how many hours per week are spent working manually doing similar workflows by hand/manually creating these designs etc..
