display radius offset diameter

[asblo]

Good morning to all

in the design of two blades for a cutting mold I found myself blasphemed because the reference radius of both blades did not seem to coincide with the result of rather complex modeling, so I thought the error was due to some passage between functions.

after several tests I realized that it is a display that solidworks returns unspoiled between two arches of center and identical radius or between arc and diameter. even on the table and on dwg remains the same visual gap, despite the odds are perfect. do you know if there is a way to solve this? because it can generate confusion.

the last image are two simple beam surfaces and equivalent diameters, but showing what I mean

I solved it with assistance. place here the solution should be useful to someone in the future, because apparently it is only a grosser view, but then in the dwg generates a real delta in the order of microns.you have to intervene on those selectors in this option screen
