If anyone else is curious about this topic they talk about using offset lines for area indication is ASME y14.5-2009 section 1.7.3
Looks like offset chain lines are the way to go for me...
thanks everyone... it seems there's a few options to chose from but what it really comes down to is that I need to be more explicit in identifying the surfaces and there isn't any explicit assumption of a tangential chain of surfaces.
Great suggestions dgallup and KENAT.
Thanks for the info guys. My question is more on other places where you'd indicate surfaces besides for surface finish callouts... E.g. if I had a flag note like the following:
"3. PAINT INDICATED SURFACES PER..."
and I had a flag pointing to a surface with other surfaces connected...
When identifying a surface on an engineering drawing, are all tangentially-connected surfaces considered part of that surface? Or do I need to identify all the tangentially-connected surfaces separately (for example: point to surface A, surface B, and a fillet that connects them)?
Per ASME...
