This option is used to calculate and display the difference between the z-value of a Tin and a given height in the project.
Continue down the page to see the Depth from Height Inquire Panel options.
To view the Depth from Height Inquire Panel, Use: Tins => Inquire => Depth from Height Inquire
Pick the <Tin> button and select the tin required.
Type in the Height that the depth will be calculated from to the Tin height.
A positive (+) depth value means that the tin is below the specified height, and a negative (-) depth value represents that the tin is above the the specified height.
Move the mouse around the selected tin and see the panel display the depth between the height and tin. The panel will also display the X and Y coordinates for the cursor position.
As shown below the panel will update as the cursor location changes.
