8.20.3. Critical Sections
If this control is activated, MDT will mark the alignment’s critical sections. Similarly, the alignment’s drawing may be configured.

Mark Length: Length of the mark situated at unique points.
Extension Length: If texts are drawn, this value sets the mark’s extension in the direction of the text attached.
Texts: It is possible either to draw the text to the Left or to the Right, or not draw the text (No text). To dimension curve or clothoid-type sections, dimensioning may be performed either in their Outer or its Interior.
