That's it

That did. Thanks.

maya desperately needs a lot of "?" fields like nuke has, where essential instructions on how to do at least simple things like these are listed. it's ridiculous to have to look up something like this... and makes me feel fortunate i do a lot of compositing these days... -_-

Maya has extensive documentation and laid out instructions on how to use tools, including this one. One merely has to hit F1 on their keyboard while in Maya.

Luckily, the correct node is automatically selected for you after running the "Project Curve on Mesh" command, so as long as you don't deselect anything, the following steps will work, otherwise you will have to find the correct node in the hypershade
  • I do not find this necessary. I'm not sure if I'm having a different experience from you guys. I can run the Project Curve command, deselect everything, even delete the original curve. Then, when I select the mesh and the projected curve and run the command, it always works.

    oh really? wow, i did not know that. that opens up a whole new world for me!

    seriously - have you ever even actually USED maya's documentation?
    sure, there are helpful descriptions for SOME tools but e.g. for this one, it's just this
    i find the documentation to be helpful in maybe 10-20% of the cases.

    Not to mention that they've misspelled "detaches", "separates" and "components" on that page. How embarrassing.

    I wonder if Autodesk would pay me for QCing their docs.

    Maybe we tried on different versions of maya?
    I have to say that some non intuitive user unfriendly tools need to change.
    How about making USER Friendly tools and USER unfriendly tools treads, so we can say which ones are which...

    Quick tip : The procedure won't work if your curve is crossed.

    This tool is useless. It never worked for us. I just tried to split a hood derived from CATIA data without success. I can project a curve fine but when it comes to actually splitting the mesh, it's a permanent no go.

    How do you mean crossed? A curve that crosses over itself, like a ribbon shape for example?

    This problem is fixed in 2013

    Try as I might I could not get this to work in 2012 but it works fine in 2013. guess it was an undocumented feature.

    Exactly.
    It can also mean that some of your CVs are rotated which creates a barely noticeable loop in your curve. Scale the tangents of each CV to make any of these loops visible.
    Or
    you can try first using the "rebuild curve" command under your Surfaces menu set.

    FYI - the comments shared in my previous post were based on using maya 2013. Also, I have since found scenarios where a screen space selection of the projected curve did result in the correct node being selected (refer to my earlier post for clarification). I do not know what makes the difference, but following the steps outlined in my previous post while using maya 2013 has so far worked for me on every attempt. So far I have only tried it with primitive curves and curves extracted from polygonal edge selections.

    I think there is more to this than just the steps. Even though it's a feature released years ago I don't think Autodesk actually finished this tool at all. It's incomplete.

    No response from Autodesk though after years of sending in the same bug.

    It only seems to work on primitive cubes and when it is used on an object more advanced than a simple box, this is all the tool seems to do:

    // Warning: line 0: Can't perform polySplit1 on selection //

    Can anyone successfully split the attached mesh in the scene?

    I've successfully used this tool on many different, very custom shapes. Maybe double check your process. Check the tips that have been offered in previous posts of this thread.
