Mouse Operation in View Port

The right mouse button is used to create and delete lines displayed in red color.

Create Line

Click on a vertex not on any lines, then click on any other vertex which can be connected to the previous vertex, a red line is created on the shortest path between two vertices. Continue clicking more points to create more lines. Finally click the previously clicked vertex again to finish.

warning

Please DO NOT click two vertices which can not be connected due to some invisible faces, which will cause the tool to crash.

Delete Line

Click on any vertex on a line to delete it.

tip

The left view port shows face selection and line editing if both the middle and right view ports are in either "Edit Faces" or "Edit Lines" mode.
