Making a techincal drawing of a part, sometime need to specify that some sorface have to be protected during the painting process.

Making a technical drawing from a part, sometime need to specify that some sorface have to be protected during the painting process.

A very easy way to do this is to color these surfaces and specify with a note on the drawing: "protect the yellow colored surfaces".

Is there an easy way to do it in SW?

Thanks for you help.
