I know these are baby steps to you and most of your readers on this forum, but remember, something is easy if you know how to do it, but getting there, that's the rub. I also really like your technique of a functional structure approach and would like to see how you would do this for the aforementioned suggested structure. Perhaps a really dumbed down tutorial, say the assembly of a box with a base and top, with an explanation of why the placement of each LCS in relation to others. In practice, they are not." The point of confusion for me was the process of using the Mapmode window and my total lack of understanding of the choices presented and which to use for a specific outcome. As Yogi Berra said: "In theory, theory and practice are the same. In reviewing the Assembly 4 documentation, I came across: "the principle of Assembly 4 is to match coordinate systems in the assembly and in the part" and I realized this was my problem.
I found that with tutorial 1 I was able to follow the instructions of how but was having trouble with the logic of why. As you can probably tell, I'm quite a rookie compared to most of the commentators. I'm still trying to figure out tutorial 2. I have read all 32 pages of comments and tried to work through the two tutorials you have given. My intuition tells me your approach will add huge functionality to this wonderful program. Zolko, thank you for the inspired work you are doing on the Assembly 4 workbench.
