What does this mean exactly

Quick question. I'm not sure what this individual is referring to exactly. Does the parallelism call-out apply to the length of the shaft? And does the flatness apply only the bottom face of the square piece?

Thanks

RE: What does this mean exactly

GD&T forum might have been a better place for this question but...

The parallelism only applied to the .20 square portion.  However, they don't specify what datum plane or axis the parallelism is to so it's an incomplete spec.

The flatness only applies to the bottom face of the square piece.

Thank you, that's what I thought. Sorry about the location of the post, I didn't have that one on my threadminder. I'll add it.  

RE: What does this mean exactly

I'd argue that the parallelism only applies to one face of the square section.  How you can define that one face out of the four I'm not sure, but there's no indication it applies to all four faces.  Again, it's an incomplete tolerance, so who knows?
