When measuring a distance on a Swiss map (or any other metric map), the obtained result is given in meters (m). Unfortunately it only shows two decimal places, meaning an accuracy of +/- 5mm. That's not accurate enough for some cases, where even a small difference has a severe impact.
In ArcMap, we could get the result in centimeters (cm), which is 100times more precise.
We ask esri to increase the accuracy of the measureing tool in ArcGIS Pro by either allowing more decimal places or by extending the units of the result to meters and centimeters.
