Definition: A section taken through the lengthwise dimension of a structure. It can also be termed as the Side Elevation of a structure.
A typical longitudinal section of a road:
Longitudinal sections of Roads, Canals, Bridges, etc are very useful in determining the theoretical gradient of the proposed structure based on the existing surface conditions.
How to plot L Section / Longitudinal Section using LXQ-CAD:
Enter the input data levels in the Initial levels datasheet. You can also enter the design levels in the respective data sheet. But it is not necessary in order to view L-Section. Now you can view the L-Section or plot the same in CAD software. You can use this view to visually enter the design levels.
