I did the tutorial myself, but then I got stuck a lot when I had to solidify some very bad files from our former supplier. the commands are many in the idd, but basically I use them in all 10/15. However the approach is mixed: half manual (cancel surfaces and reconstruct them), half automatic controls (with which you never know if there will be important changes to the basic geometry). Fortunately, however, we are never required to have very precise external files, it is enough to store interface surfaces with our components.
