shared parameters

[wags5116]

Can you edit the shared parameters that are already created?

You can't edit the txt file and after they are made some fields are grey'd out.
I'm going to say no.
I think it has to do with some GUID # that cannot be re-associated or changed.
There might be a 3rd party app I don't know of.

Have you used it yet? If yes then you'd have to remove it and replace it with the revised version which is essentially starting over anyway. If not then it is possible, though not supported or suggested, to alter the shared parameter file directly.

The unique GUID and the related information once used/applied to families or projects effectively means you've got to start fresh. If you realize you made a minor error before actually putting the parameter into play...you've got a tiny window of opportunity to fix it before you've got a "do-over" experience.

I've written a lot of posts about parameters on my blog, here's a POST that provides a summary and links to several including one that is relevant to your question, called Walking on Thin Ice.
