Section calculates the section properties of a cross section as you draw it.

Draw your cross section counter-clockwise. Double-taps will create a vertex. Single taps near a vertex will select that vertex.

Selected vertices are green. The section's center of gravity is shown as a blue circle. The section's principal axes are shown in blue. Theta is the angle between the coordinate axes and the section's principal axes.

Vertices can be dragged from one position to another by tapping close to the vertex and dragging. New vertices will be created counter-clockwise from the selected vertex, dividing the green edge. The position of a vertex can be precisely placed by selecting the vertex and entering coordinates into the input box in the format X, Y.

Three icons at the bottom of the screen will recenter the axes, delete all vertices, and delete the selected vertex.

The entire screen can be panned by dragging a finger on the screen away from a vertex. The entire screen can be zoomed in or out by pinching.
