Moving vertex of matrix border

Editing of a separate vertex of matrix border (change its planned location) is executed by moving cursor with pressed left mouse button. Moving of cursor with the released button does not change a vertex location.

Choice of a vertex is made by move of cross in a work area without mouse button pressing.  At  that the auxiliary line connects the cursor position and nearest object vertex.

It is recommended to do rough vertex positioning by mouse and to use arrow keys along with pressed left mouse button for precise vertex positioning.

Saving of matrix border is made at the moment of completion of executed operation.

At activation of Move border vertex mode the matrix map is displayed entirely, without taking into account a border. After completion of the executed operation the displaying of matrix is restored into initial condition.

Way of activation of Move border vertex mode:

In Matrix list dialog ( View \ Matrix list) choose a matrix.

Then press Properties button and in the appeared menu choose Edit border item.
