If the spot heights or points are not displaying on the IRRICAD screen they have been inadvertently turned off, possibly by typing the two-letter code without realising it.
To turn on the display of spot heights and points type ti on the keyboard.
Note that if the spot heights /points display is off when Import from Google Earth is actioned the image will appear very small on the screen. In this case start a new design, turn the points on by typing ti and then Import from Google Earth again.
Tip:- If your design does not fill the screen when using Zoom All and Select Window, Invert Selection, Delete does not delete outside objects this may also be a symptom of the points display being off. Turn on the display of spot heights and points by typing ti and try Select Window, Invert Selection, Delete again.
