How to add a surface finish note to an assembly model 2D drawing?

[thollotrich]

I'm trying to add a surface finish callout for a part that gets ground. No matter what I try I can't select the surface I need. The model is from an assembly file that gets a revolve operation from a part file to show the finish grinding process. It seems like it doesn't like that but I'm not sure. Any help trying to place the symbols?

I think you should provide more context.  Are you trying to do this in the model, or in the drawing?

What help documentation have you read?

this is from a google search: (creo help surface finish)
