Transform Vertices Tool - VEditBox.dll
This tool can be used to distort a set of vertices by manipulating a box around them.
If the tool is activated in Vertex Mode, a bounding box appears around the selected vertices in the 2D windows. The four edges of the box can be dragged in any direction by the small dot in the center. This way, shapes can be arbitrarily distorted, like the sphere above that is forged into an ellipsoid. The tool is switched off by pressing [Esc].
