Auto draw

Application

When the Auto draw function is active, the control draws the contour that you are programming in the Contour graphics workspace.

When you shift an auto-drawn contour into the Sketch plane, you can edit or export the contour.

Description of function

Auto-drawn contour from the NC program

The control highlights the auto-drawn NC block numbers in gray.

When the Auto draw function is active, you can program only path functions, except for approach and departure functions. For other NC functions the control will show an error message (e.g., for a cycle call).

The contour starting point must be clearly defined in the plane, which means, for example, it must include X and Y coordinates.

 
Tip

HEIDENHAIN recommends using the Auto draw function only during contour programming.

Auto draw a contour

To have a contour auto-drawn:

    1. Select the NC block from which the control starts auto draw

    1. Activate the Auto draw toggle switch
    2. The control opens the Contour graphics workspace, if necessary.
    3. The control highlights the NC block number of the selected NC block in gray.

    1. If applicable, open the List column

    1. Hide the Sketch plane

    1. Program the next contour point after the selected NC block
    2. The control auto-draws the contour element in the Auto draw plane of the Contour graphics workspace.
    3. Program further contour points as needed
     
    Tip

    If you mark several NC blocks and then activate the Auto draw switch, the control will draw the complete contour that has been marked.

    Notes

    • The control only auto-draws a coherent area with max. 200 NC blocks.
    • To induce the control to draw a rounding RND or a chamfer CHF, you must also program the next contour element.
