Can we get range of tessellation control parameters ?

Hi all,

We can save model to .obj format, There is a option (particularly after selecting uv map),  we can set values for Chord height, Angle control and step size. these controls the level of tessellation. There is range of allowable values are shown if we mouse hover over these controls.

Can programmer through API get this range, max min and suitable values? I do not found anything related this.
If I am tessellating surfaces pro grammatically this will be useful to have control over the tessellation.

Thanks in advance.
