Creating A Local Corner Relief

This task explains how to define a corner relief locally on a set of bends.
Depending on the number of bends involved, not all types of corner relief are available.
Open the CornerRelief02.CATPart document from the samples directory.
The part needs to be unfolded prior to creating the corner relief.

  1. Click the Corner Relief icon .

The Corner Relief Definition dialog box  is displayed.

        

  1. Select the supports on which a corner relief should be created.

By default the User Corner Relief is active in the Corner Relief Definition dialog box.

  1. Select the sketch, directly in the document.

As soon as the sketch has been selected the sketcher icon is displayed in the dialog box allowing you to edit the selected sketch, if needed.

  1. Click OK in the Corner Relief Definition dialog box.
         

  1. Fold the part to check the corner relief in 3D.

You can use the Catalog icon to open the Catalog Browser.

If you choose another corner relief type, the scenario maybe slightly different:
  • circular: by default the corner relief center is located at the intersection of the bend axes.

You can select a point as the circle's center.

A radius is proposed by default. It is equal to the bend radius + the thickness. You can change it by:

  • Selecting Formula -> Deactivate from the contextual menu of the input field and enter a new value,
  • or clicking on the button and entering a new formula.

  • square: the square corner relief is created using the bend limits. Its dimensions are defined by the width of the unfolded bends.

Available between two bends only.

  • triangular: the triangular corner relief is created from the intersection point of the inner bend limits towards the intersection points of the outer bend limits with each wall. 

Available between two bends only.
