Map: Height Maps

[zovs66]

Hmm, I must be doing something wrong, I followed DRG instructions in post #190 (I have the full paid for version) and the first time through per the instructions here:

"After opening the map go to second page of tools (either by clicking the blue triangle or "n" key on your keyboard) and choose
clear keeping the current contour"

That just clears the map of everything including the contours. The second time through I did not click the clear button and the contours stayed by the map is still a big empty blank map.

I tried both selecting block fill and 1-90 fill, nothing changed.

I don't know?
