Volute > Cross Section > Line Segments cross section

The shape of a Line segments cross-section is described by a series of line segments.

One half of the shape of the cross-section is initially based on line segments arranged in a trapezoid shape. Points 1 and 4 are the fix start- and endpoint.

All corner points are connected by line segments. The coordinates of each point and the related corner radius can be adjusted in the context dialog:

Coordinates and radius of vertex

Using the context menu of a line segment, points can be added at the cursor position or be removed:

When moving points the following constraints can be enforced by pressing a key on keyboard:

CTRL	Point moves on a circle around the previous point. The radius stays constant while pressed.
CTRL + SHIFT	Point moves on a circle around the next point. The radius stays constant while pressed.
ALT	Point moves on a line between its last position and previous point.
ALT + SHIFT	Point moves on a line between its last position and next point.
