Creating a Hole Curve

Hole Curve lets you create the curve definition of a hole on a surface.

Before you begin:

Create a 3D shape containing a surface and a point.

  1. Select one of the following shapes: Round, Slot (elongated hole), Rectangular, or Square.

    The shape is defined on a plane and projected on the surface along the defined direction. The nearest projection is used.

  2. In the Center Point box, select a point.
  3. In the Support surface box, select a reference surface.
  4. In the Orientation box, define the orientation to align the major axis along the direction.
  5. In the Punch direction box, specify the direction.

    • If the point lies on the support surface, by default, the punch direction is the normal direction at the center point.
    • If the point does not lie on the support surface, you must define a punch direction.

  6. By default, the Axis Computation check box is selected to automatically create an axis and direction lines passing through the center of the hole.

    One of the direction lines is created along the input orientation direction. The other direction line is created mutually perpendicular to the axis and the first direction line.

  7. Select the axis type.
  8. To create the axis along the punching direction, select the Axis Normal to Surface check box.

    The axis lines are created in the normal direction to the support surface.

  9. To specify the shape dimensions, do one of the following:
    • Click the value to edit.
    • Click the Size tab.
  10. Click OK to create the hole curve.

Note: If several solutions are possible, the solution with the minimum distance is chosen. If all distances are equal, a message is displayed, asking you to modify the point position.
