Yet, get_graphics is to get system faceting of geometry, not a user set mesh. So Angle tolerance is more important than distance tolerance for curved edges and less important than distance tolerance for straight large differed edge lengths. </span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span><br></span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent;

If not, then the system is not using this option; or can you change the tolerance to 5 for a circular edge to see if you get 73 points; or change the tolerance to 1/36 for the same edge to see if you get 73 points. I wouldn't think it uses the tolerance for a distance, but I could be wrong.</span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span><br></span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span>Now in cubit13.1, it added more accuracy to several functions, including reflect and
