TNCscope features a cursor for measuring a curve. The cursor is a small cross that "rides" along the active curve when the mouse is moved.
The graph header always displays the current position value in the X and Y directions. If you have activated vertical auxiliary cursor 1 or the horizontal auxiliary cursor, the difference in relation to the respective auxiliary cursor is shown.
The View > Show Cursor Values command displays the momentary value directly next to the cursor.
Position the cursor by moving the mouse horizontally. Use the left and right arrow keys for exact positioning of the cursor. With the <Home> and <End> keys, you can place the cursor at the beginning or end of the active curve.
Freeze the current position of the cursor with F4. This is useful if the cursor is to be at a certain position on a printout, for example. Press F4 again or click anywhere in the diagram to release the cursor.
If the cursor does not move when the arrow keys are pressed, then the diagram is not the input focus. In order for it to receive the input focus, click anywhere in the diagram or press F6.
