Path Selection
This page covers the Path Selection tool in Cinema 4D. It selects edges or points by painting along them in the viewport, making winding edge paths quicker to pick than with loop or rectangle selections.
The Path Selection tool lets you select polygon edges or points interactively by practically painting over a selection. This tool only works in Edge or Point mode.
Note the functionality of the Move, Scale and Rotate tools by which you can create a selection path between the currently selected components and the previously selected components by Shift + Ctrl/Cmd + clicking. This works in Point, Edge and Polygon mode. Note also the similar Loop Selection function.
