Maya Python cmds.polyToCurve missing documentation??

[such8]

Hi

I cannot find the documentation for the cmds.polyToCurve python command. This is an existing command, as you can see on the screenshot it is correctly highlighted, and the code does run. 

But when I search for it in the documentation, there are no results.

Why is this? Where is the documentation for this command?

Thanks for the sharp eyes, it looks like this command didn't get documentation written for it. I'll file an internal request to get that added. In the meantime the documentation for the polyProjectCurve command can give you a good idea of what's available, and of course "cmds.help( 'polyProjectCurve' )" will give you the expected syntax as usual.

Thank you for getting back to me. I was relying so heavily on the documentation, cmds.help completely slipped my mind. Now I at least know which flags to use. Thanks.

My original issue however still remains. This is what I am trying to achieve:

I have a selection of edges:

And I want to convert it to a curve. When I do it with UI commands this is what happens:

I would like to do achieve this with python commands.

But when I do this:

I get the following error:

Which tells me that I can't use the command for multiple edges? But clearly it works with the UI commands.

I tried to get around this by calling polyToCurve() for each selected edge separately, but that doesn't give me a smooth curve, just straight curve segments, as expected:

Do you know how I might be able call polyToCurve for multiple edges at once?

That's a two-fer - a completely different problem, hidden by the missing documentation. For some reason (the question which I'm appending to the documentation request) when you pass objects to the command it only accepts a single edge but when it uses the selection list it can accommodate an arbitrary number of edges.

The solution for you is to just call "cmds.polyToCurve()" without passing in the selection list.

Thank you! You really helped me out.
