I'm newer to the fourm and I went through several threads trying to find an answer like yours. This was an excellent response and helped support my theories with profile vs. Meaning, pronunciation, translations and. *actuall the delineation is a little more nuanced than that (rFOS is defined by specific shapes ie: cylindrical/circular element which are associated with diameters or iFOS can contain/be contained by an AME) however 'opposed points' is the most simple way to intuitively explain it in a general sense. Semi-circle definition: A semi-circle is one half of a circle, or something having the shape of half a circle. Diameter when Dimensioning Semi-Circle ctopher (Mechanical) 24 Aug 20 14:57 *actuall the delineation is a little more nuanced than that (rFOS is defined by specific shapes ie: cylindrical/circular element which are associated with diameters or iFOS can contain/be contained by an AME) however 'opposed points' is the most simple way to intuitively explain it in a general sense. Fjordur is a very beautiful map and the developers have added a In this article, we will tell you about a place present in the ARK. Even at exactly 180deg the containment of a UAME by a real as-produced surface may still be unstable, especially if the flexibility of the part and associated gauging elements are considered. Finally, another brand new map of ARK Survival Evolved has been released which is named Fjordur. If you were to change the directly toleranced dimension to a diameter and apply a position tolerance, you could be technically correct as it can technically contain a UAME (has opposed points) but you should know the limitations - any deviation in the intersecting surface can result in a semi-circle of less than 180deg and an unstable UAME. There have been many discussions here about alternate dimension/control schemes for 180deg semi-circles, a quick search will bring up several, but profile is by far the most robust. Learning Circle Drawn from Building a Discipling Culture by Mike Breen, Making Room for Life by Randy Frazee, and The. Personally for such a feature profile would be the ideal control. I'm not sure if theres anything which strictly prohibits it, but a FOS must contain opposed points* so it should be attached to the dimension, or control (ie: a profile tolerance on an iFOS like Y14.5-2009 fig 8-24) which suggests opposed points. Whether its called out as a radius or diameter makes little difference to a profile tolerance, as long as its basic, though radius might be the most intuitive in this case.Īpplying a position tolerance to a radius dimension, regardless of what the actual feature looks like, is questionable at best. What standard are you adhering to? Is it ASME or ISO, and what version?
