Creating a Circular Cutout

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

Open the Hole1.CATPart document.

  1. Click Circular Cutout .

    The Circular Cutout Definition dialog box opens.

     
     
  2. Select the Point that will be the center of the circular cutout.

    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 circular cutout 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 circular cutout is previewed with default parameters.
       
     
  4. Select circular cutout 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

     
    Circular Cutout types do not affect the circular cutout geometry.
  5. Define the value for the diameter of the circular cutout in the Diameter field.

    If you change the Radius value using the spinners, the preview of the circular cutout 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 circular cutout (identified as Circular Cutout.xxx) is created and the specification tree is updated accordingly.

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

Create Cutouts from a Sketch

  1. Select Circular Cutout in the Holes toolbar.
    The Circular Cutout Definition dialog box opens.

  2. Select the Sketch on the geometry or in the specification tree.
    A preview is displayed.

  3. Click OK to validate.
    The circular cutouts (identified as circular cutout.xxx) is created and the specification tree is updated accordingly.

Create Cutouts from a Mapped Curve

  1. Select Circular Cutout in the Holes toolbar.
    The Circular Cutout Definition dialog box opens.

  2. Select the Mapped Curve on the geometry or in the specification tree.
    A preview is displayed.

  3. Click OK to validate.
    The circular cutouts (identified as circular cutout.xxx) is created and the specification tree is updated accordingly.

Create Cutouts from a Projection

  1. Select Circular Cutout in the Holes toolbar.
    The Circular Cutout Definition dialog box opens.

  2. Select the Projection on the geometry or in the specification tree.
    A preview is displayed.

  3. Click OK to validate.
    The circular cutouts (identified as circular cutout.xxx) is created and the specification tree is updated accordingly.

When the profile is not only composed of points, the constituents points of the profile are used to create the cutouts, as well as for the sketch, the mapped curve or the projection.
