Okay, stuck again. Really stuck this time, I think.

I've been back and forth from my cr2 to the Open Boat cr2, and where things break down is the hip. My cr2 doesn't have one, the Open Boat does - I'm assuming "hip" is just the internal name for Hull. Welding is done to the hip a lot, as in:
    weld    boom:2
    hip:2
    weld    mainSail:2
    boom:2
    weld    gaff:2
    mainSail:2
    weld    pulleyBoom:2
    boom:2
    weld    pulleyDeck:2
    hip:2
    weld    schotMain:2
    pulleyDeck:2
    weld    schotMain:2
    pulleyBoom:2
    weld    foreSail:2
    hip:2
    weld    lSchotFore:2
    foreSail:2
I'm taking this segment to mean:
    weld    boom:2 ...to... hip:2
    weld    mainSail:2 ...to... boom:2
    weld    gaff:2 ...to... mainSail:2
    weld    pulleyBoom:2 ...to... boom:2
    weld    pulleyDeck:2 ...to... hip:2
    weld    schotMain:2 ...to... pulleyDeck:2
    weld    schotMain:2 ...to... pulleyBoom:2
    weld    foreSail:2 ...to... hip:2
    weld    lSchotFore:2 ...to... foreSail:2
So, it kinda makes sense. The pulleyBoom and the pulleyDeck are pointed at each other, and the schotMain (which is your mainsheet) is pointed at the pulleyBoom. Welding of the pulleyBoom to the boom ensures they'll be inseparable as does the welding of the pulleyDeck to the Hull. Yeah, I can do that to the Daysailer too... so I did.

However, whenever I tried to do Point At stuff, things went catty-whompus. The boom tweaked, the mainsheet shrank and flopped, and nothing seemed to work. I got the sense that some underlying force was not being properly dealt with.

But what?

I noticed that when you do a Create New Figure from the Hierarchy Editor dialog - so that it ends up in the New Figures folder - the resulting .cr2 has the geometry embedded in the first part of the .cr2 and there are no groups under channels. IOW, no place to add a Point At groupNode.
After loading that boat from the New Figures library, and saving it to my folder as a .cr2, it took out the geometry - creating an obj file to hold it in - yet only the Hull actor has as sub-entry groups under channels.

"Groups..." I thought, "where are groups set up? Set-up room?"

Well, I took my little boat - the one i had just loaded from my own library, from which obj stuff had been separated - into the setup room, and lo and behold, I saw bones. Bones that need to be appropriately accounted for and dealt with.

Back to loading the Open Boat and check out the bones. There's got to be a more systematic approach to all this - I feel like I'm chasing my tail....

Should probably stop for lunch....
