For the representation of contours the options shown in the following input window are available:
Default colour for presenting contours (variable XSUSIKontPen)
Setting the default marker for point contours: variable XSUSIKontPmark and setting the height of the marker with: XSUSIKontHeight
Setting the default marker for line contours variable XSUSIKontLmark and setting the height of the marker with: variable XSUSIKontHeight
If one of these options is changed in the options menu, this has no effect on the appearance of existing contours. Their presentation attributes can only be changed via the menu Layer 
Modify colours.
A modified parameter of the contour presentation is used only when opening a new project. Changing the types of marker and the height of the markers of an existing contour layer is not possible.
