Measurement tool

 

Hello everyone, 

I don't know if this is the right post for this, but for programming I often use the measurement tool, especially to measure angles between surfaces. I have a problem when I want to measure an angle between a hole (its axis) and a surface. As shown in the following image, I get different values ​​for each measurement, and never the correct one here: 90 degrees. It seems to be between an axis and a plane (I didn't have this problem in V5). Is this a setting to be made? Does anyone have a solution?
