When creating a Cross Section, the data is projected on the 2d model left to right using the line direction. The first point of the line ( or SmartLine ) defines the left of the 2d model; and the last point defines the right.
If the line you are using does not have the right direction, you can change it
- Type in “key-in” in the text window
- Enter "change direction"
- you will be prompted to select and element and will be able to change its direction
