A more thorough explanation than I originally provided just to be clear…….
If you have a primitive and a curve, and are attempting to Attach To Motion Path, Maya doesn’t care about selection order, the object will always be attached to path regardless order of selection. If you have two curves selected, and attempt to Attach To Motion Path, the first selected curve will always attach (constrain) to the second curve. If you have two objects selected, either two objects, object and curve, or even two curves, and attempt to point constrain, the second selected object will constrain to the first. (as already noted by another poster) If you have two primitives selected, and attempt to parent constrain, the second selected object will constrain to the first (as already noted by another poster) If you have two primitives selected, and attempt to parent, the first selected object will become child of the second Resistance is futile… (BTW, a note about Attach to Motion Path. This is essentially a “MotionPath constraint” but it is not directly presented as a constrain. You can delete the uValue node attached to a MotionPath node and you get the functional equivalent to a curve constrain in Soft allowing the user to arbitrarily constrain the object to any place on the curve without having to keyframe. You can create tank treads by setting additive expressions from one tread MotionPath uvalue to another once the uValue curve nodes have been deleted and all the treads can then be driven by only one tread element. Because it’s not presented as a curve constraint the way SI’s curve constrain is, it is not immediately obvious that this type of constrain is available to you.) -- Joey Ponthieux __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.

What if I select a sphere, then a curve second, and attach to motion path so the sphere constrains to the curve. But, if I select a sphere, then a curve second, and constrain point the curve constrains to the sphere? What the…! Why isn’t the context the same? Why isn’t the directionality the same? Why do I have to spend time thinking about this before I do each procedure? Is it source -> target, is it target -> source, or is target-> …..? Huh….what’d you say?…. What?! I can do what! Oh geez!.... no……, You’re telling me that the attach to motion path has no context? You can select either one first and it doesn’t care? I’ve been deceived into thinking directional context mattered for over a decade because it makes more sense to select the object first and the path second? You know, source -> target, start -> end, throw -> catch, 1->2? But the context for constrain is rigid you say? The context for attach to motion path isn’t rigid? Really? And constraints work by the throw doing the catching? 2 is first and 1 is second? Source receives and target sends? These contradicting behaviors have been there for so long I doubt anyone can tell you why they are this way. Add to that the fact that Maya is largely used in teams that are task centric, I’d argue its possible that a lot of people who use Maya have hardly noticed what the generalist who is using every part of the app will notice. For the record I complained to AW mightily, about many of these inconsistencies you are observing, back in the late 90s. I always got the sense they were so deeply invested in the meat and bones of the algorithm or giving the core interior of the application more functionality that they just did not have interface issues on their radar. The Humanize Maya folks have a significant amount of work ahead of them…. -- Joey Ponthieux __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.
