Digitise - Adjust Vertex Position

(This option is not available on the Freeware version)

This option allows you to adjust the position of vector end points - the vertices within the vector polylines - of the vector drawing.

Enter the Adjust Vertex mode by clicking the Adjust Polyline Vertex toolbar button (or the Vector->Digitise->Adjust Vertex Position menu option).
The cursor will change to a Adjust Cursor crosshair to indicate that the adjust mode is in effect.

First you select a vertex to move by clicking near to it, then you use the mouse to move the vertex to a new position. While you are moving the vertex WinTopo Pro shows the connecting vectors moving (rubber banding) as well, so that you can see exactly what the result will be before you click to put it in the new position.

To quit the operation without moving the vertex you can click the right mouse button. Alternatively, you can press the Esc key, or click the Adjust Polyline Vertex toolbar button again.

Snap Modes

The Snap mode options have no effect before you select a vertex. The target square will jump to the nearest vector end point to the cursor.

When you are moving a vertex to a new position the snap modes will operate to allow you to position the node accurately. See Snap modes for more information.


If you make a mistake, or want to redo a point, then you can click the Undo button undo toolbar button. The last digitising operation will be undone.
