Clicking the Interpolate button to start interpolation. Then click the OK button to close the form.
After the interpolation process is done, RMC on the grid layer then select Show Properties / Bottom Elevation to display the bottom elevation of the grid after its grid nodes are assigned elevation values as shown in Figure 10.

An alternative approach to interpolating the bottom elevation of the selected grid is using a polygon.
Selecting the Add a new polyline button from the main toolbar then start drawing a polygon that covers the grid as shown in Figure 11. Change the cursor to select object mode (press the S key or select the Select Object in the main toolbar). Selecting the overlay layer (layer contains the polygon), then LMC on the polygon (it will be highlighted by changing color to red), then RMC to display options, select the Interpolate Grid Elevations option as shown in Figure 12. The message will be shown up as shown in Figure 13 after the interpolation process is done. Click the OK button to close the message.
