measurment angle???

[[Fl...]]

hello friends,
I have the next questions?
how do I correctly request the measured value for this angle, 30 grades from the origin??? is the angle from 2 d line and center of parts. i attached the pictures. is correctly with angle between feature or with another???

Create a symmetry point between the two 6mm edges, then construct a 3D line between the two symmetry points. Project 3D lines to the top plane then you can check the angle in projection angle A1 or A2 depend upon your alignment.

thank you for information, but i have another question: when i make the symmetry point between the two 6mm edg is necesar the polar coordinates for make the corectly point but Dont work modify in polar cordinates, only in the normal coordinates. i attached the photos.

I am at home now, due corona problem we have 21 days shutdown here, so I can't check in calypso wheather it can edit or not. I think it can edit. I did it lot of time in Cartesian coordinate not in polar.
If you have more area try to create a symmetry plane, l mean single plane not two plane.
