Is there a standard way of annotating surface texture of injection molded parts on the 2D drawing?  Anyone have an example they can share?  My toolmaker is asking for a texture map (which has a different meaning in SW so search doesn't help too much) showing where to apply an SPI-B1 surface finish, where apply mold tech 11000 texture, etc.

Is this based off the surface finish symbols used with machined parts?  Is it just a general text note?  Any best practices to suggest such as use of hatching to show all like surfaces (although I suspect this would get quite cluttered quite quickly).

Thanks
