Draw Contour

Instead of clicking along a structure, the draw tool can be used.


By holding the left mouse button and dragging the cursor along the desired trajectory, a polygon with dense vertexes can be generated.


The contour is closed, as soon as the mouse button is released. This contouring mode generates many closely spaced vertexes. To view the contour more clearly, the vertexes can be hidden.
