I came across a surface profile call out. It associates with a basic dimension too. What is the relationship between the basic dimension and the surface profile?
 
The basic dimension set up the theoretically perfect surface. The surface profile basically describes how much it can vary from that.

Surface profile can be equal bilateral, unequal bilateral or unilatera.

Take a look at ASME Y14.5M-1994 section 6.5 if you work to American drawing standards.



This is a pretty basic level question, you really need to do some reading and preferably get some training if possible.

KENAT,

Have you reminded yourself of faq731-376 recently, or taken a look at posting policies:
