Set the watershed for the surface style

QQ netizen 1109743151 for help,

Does not display after setting up a watershed.

There seems to be no problem in the code,

after testing,

It was found that during the manual setting of surface styles,

If a watershed is displayed,

There will be a process of surface analysis,

So the code for surface analysis is added to the code,

The watershed can then be displayed normally.

The test code is as follows:

Posted his code without the permission of netizens,

Hope there are no misunderstandings!
