Measuring a circle in contour feature without Curve?

[[Ch...]]

Hello,

Does anyone have an idea how I can measure the distance 17.87 with respect to 2 theoretically fitted circles Ø5mm without curve?

Measure 2 lines up and 2 lines down ( as show on picture ) and use tangent feature to fit TED circle to obtain that measurement.

Selbstzentrierendes Antasten mit einem Taster Ø5 von beiden Seiten und dann dann Abstand (Kugelmittelpunkte! + 5mm)

Für das Maß 16,6 Kugelmittelpunkt +2,5mm.

Thank you very much for your help. I approached the matter in a much too complicated way.
