No.. It won't help. I tried to set DimRoundOff to 2..and Then I get 450 from 450.955465...But, it is not ok, because, when I set this value to 2 and set precision to 0.0000000, dimension shows me 450...
I don't want dimension to show me 450 if precision isn't 0. So, I want to have dimension 450.9543215, and when I set precision to 0 I want to have 450.
