Creating a Circular Cutout

This task shows you how to create a hole, that consists in removing material from a body.

Open the Hole1.CATPart document.

  1. Click Hole .

    The Hole definition dialog box opens.
  2. Select the Point that will be the center of the hole.

    It can be either a sketch containing one or more points, or a point, or several points.
    • The point can be selected anywhere in the geometry, not necessarily on a surface. In that case, an orthogonal projection will be performed.

    • You can also directly click the surface: a point will be created under the pointer. 

    • To deselect a point, click it in the specification tree.

  3. Select the Support object where the hole will be positioned.

    The support can be different from the support where the point lies. In that case, an orthogonal projection will be performed.
      The hole is previewed with default parameters.
  4. Select hole type:

    • Clearance: defined with a center (point) and a radius

    • Index: used to measure and validate parts

    • Manufacturing: used for manufacturing (for example to fasten a part on an equiment

    • Fastener: used as a rivet

    Hole types do not affect the hole geometry.
  5. Define the value for the diameter of the hole in the Diameter field.

    If you change the Radius value using the spinners, the preview of the hole automatically updates. However, if you enter a value directly in the field, you need to click the Apply button to update the preview.
  6. Click OK to validate.

    The hole (identified as is created and the specification tree is updated accordingly.

    Holes can be created on the flattened part and on the bend in case of a flange.
