How do I change the value of the Fresnel Zone used in path profiles shown in HDPath?

To change the Fresnel zone value used on the path, click the Fresnel label in the Path Settings area to open the Fresnel section:

Path Settings fresnel

The Fresnel zone is drawn using the frequency from the left side (transmit) facility information.

You can change the Fresnel zone number and ratio in the Fresnel section. For example, using even-number Fresnel zones and a ratio of 1.0 can be useful in checking for reflection points on a path:
