tilt orientation tolerance on conical surface

[czar]

hi, I have Japanese colleagues who have forwarded a design where a flange has a trunk-conical hole on which they applied a control of the angle with a tilt tolerance, the value of the angle is expressed as theoretically exact size and the plane of reference is the planar surface of the cylindrical flange.
I am not so sure that the inclination can be applied to entities that are not axes or planar surfaces...an axis of a sloped hole compared to a planar surface there is, a surface with a surface also, but I would say a cone (male or female) should be controlled with other types of geomentary tolerance, coaxiality, profile, total oscillation, in theory I should get two equidistant surfaces between them from the theoretical one.
What do you think?

ah... in the box of geometric tolerance there is no ø diameter symbol

found! becomes a 2d control applied to all lines forming the cone, basically creating two cones equidistant from the theoretical conical surface.

angularity dimensional:​

as stated before: 2-dimensional references can also be used with angularity to ensure that an angle is met around a round or complex feature. if you wanted to specify the angle of a cone, for example, the angularity would apply to each line element along that cone referenced to the bottom of the cone.

Where did you find this?

Hello, I read only now:

Angularity | GD&T Basics

Angularity is the symbol that describes the specific orientation of one feature to another at a referenced angle...
