This documentation was written for releases up to 2018 and is being revised. Some dialogs have changed since. If something does not match what you see, write to [mc@mcgrating.com](mailto:mc@mcgrating.com).

The purpose of this page is analogous to the purpose of the ***Scanning*** page and the meaning of most fields is obvious. The coordinate system is illustrated in ***Service Window*** then ***Structure Geometry***.

- If Check Box ***2D (x, z) Scan of*** is not selected then depending on the ***Scanning Direction*** and*** Cross-section ***options the user will get all field or power flow components distribution along any axis at selected coordinates along other two axes.
- If Check Box ***2D (x, z) Scan of*** is selected then the user will get a distribution (along any two axes at selected third axis coordinate) of field or power flow component selected in the Combo Box at the right of Check Box ***2D (x, z) Scan of.*** Scanning range and number of points can be selected individually for both directions under appropriate ***Scanning Direction*** option. The final state of this control defines rows in data table.

All changes in this page do not impose a recalculation of the structure. By default this page is disabled. To enable it select an appropriate option in the ***Options*** page.
