Circle deflection
 

Hello everybody:
I am trying to mesh a shape in which there is a circle, but when I want to mesh a quarter of the circle (picture 1) it deflects after meshing and is converted from a curve to a line (picture 2)
does any body have any idea?
Thanks for your help

You might select the connector in question, and from the Grid menu select Distribute.. On the Break Points tab ensure there aren't any Break points that are preventing the linear portion of your connector from being dimensioned with grid points. If there are, as I suspect, then simply expanding the Delete Break Points frame and clicking on the Delete Break Points button should resolve the issue for you.
