WOW! Thanks for the link! Those are cool options! The more I learn about this software the more I like it!
I've said this before, but I'll say it again... your artistic and innovative approach to handling the standard 3d modelling features is what really sets you apart from everybody else!
I would never have thought to add holes in a model by creating a slab and mirroring it... but having seen it done now, it makes so much sense to do it that way! And mirroring has the added advantage of making the resulting model more symmetrical and pleasing to the eye!
I can see I'll be spending a lot of time here reading through the forum and watching the tutorials... I am very happy with this purchase, and I can tell already that it is destined to become one of my go-to solutions.
