Dear Dr.Ramya, Thank you for your inquiry. We apologize for the delayed response.
Unfortunately, the feature to set a virtual plane with an arbitrary angle added to a specific plane is not currently available.
As an alternative, when setting measurement values, you could define the angle measurement based on the FH plane as a reference and input a value that is 7 degrees smaller than the mean value of your reference data for comparison.
We will internally discuss potential improvements to the measurement wizard in relation to this matter. Thank you.
