Measuring angle crossing 180 degrees back and forth

Greetings all!

I'm a bit stuck and need help. I need to measure an angle similar to what you can find in the model. Depending on circumstances, angle can be less or more than 180 degrees. And here I have a problem - it is measured as either inner or outer, depending on the setting. Therefore I can't get the needed result, it always an error in one of the cases. How to model measurement that will automatically switch between inner and outer case to get consistent results?

Not sure what the problem is. There is no 'error' when you go over 180 degrees. You either get an 'Inner' or an 'Outer' angle, whichever option you've chosen.

Could you be more clear as to what it was that you were expecting?

Hello John!

The problem is that angle measurement is either inner or outer - and the angle I need to measure can be one time less than 180, net time more than 180. But when it crosses 180 to something over that value, the measurement remains inner and still shows less than 180. The same with the outer angle. I have found a workaroud and attached it to the post. If you have a look it will be more clear. Maybe it is possible to model this measurement in a more straightforwar way?

I was going to suggest something like that.
