Not really, its obviously easy even if its your first try, if you can't figure out how to operate Rotondo's doors, it just proves your stupidity.
You need think about the overwhelming amount of information. If you're used to working with the 3 numbers on regular bricks, now you're suddenly bombarded with hundreds of lines of numbers, text, and characters. You need a minute to get your head around that. Once you know something it seems simple.
When I first saw Blender I was really discouraged by the interface and now knowing where anything was. So much so that I simply didn't touch the program for weeks. Now I can use Blender without any problems.
well that depends on the build. if you just wanna build some simple LEGO-like house then one of those flat doors will do.
You are limited to standard LEGO houses when using Rotondo's doors. You can't use flat wooden doors in a space ship or a submarine. it doesn't fit.
it's also about having as many details as the build itself. I like details, because it makes builds different. and so I prefer JVS.
Why would BLBs prevent you from having details? I don't remember there being a quad limit on BLBs like there is on DTS. The collision mesh is actually better on BLB doors since they actually have collision while open.
My only problem with BLB doors is the lack of animation which is really neat on JVS doors. Otherwise I'm all for BLB doors.
