Question:

Why do my DTM sections appear as straight lines when I know the section is not level

Answer:

The most common reason for this is not using consistent units between horizontal and vertical dimensions. For example if all your spot heights are in metres but you scale the survey so that horizontally it is in millimetres then the horizontal scale will be 1000 times the vertical scale. Luckily Caddie has a vertical scaling factor for sections to allow for this. If your horizontal scale is in millimetres but your spot heights are im metres, just set the vertical scaling to 1000 and the sections will look correct.
