Hi,
I'm sorry but there is no such function in CadTools. However you can type in any station in the input box named "Station" and then hit the Refresh button. This procedure will place the cross Section preview at that station.
To plot that section (current Section) select any of the two options "Current Station as Cross Section" or "Current Station as 3D section". The first option will let you select a point for the cross section, the latter option will plot a 3D section placed at correct location relative to the alignment (selected 3D polyline).
After plotting the Cross Section you may enter a new station, hit "Refresh" and repeat the plotting etc.
