The other day @TheOnlyAaron posted a new Skill Builder video that shows a handy way to position a component in an off axis situation. Well worth a few minutes to watch it.
I use a different method and did a video to show how I go about adding these sorts parts. I actually do this for all sorts of objects, not just those that are off axis. It’s not necessarily better, it just uses a different workflow leveraging the power of components. Mine doesn’t have the nice opening like Aaron’s does. I hope Aaron doesn’t mind this alternative method being posted.
