Before you begin: Open a 3D shape containing three intersecting fillet surfaces with equal radii.
-
From the Corner Type box, select Ball.
With this corner type, a ball with the specified value is positioned in the corner. The connecting surfaces between ball and fillets form the ball corner, thus ensuring that the minimum radius is directly applied on the ball surface.
For this corner type must be selected as input elements three fillet surfaces created with the Advanced Fillet command. No other input type is accepted as valid input, i. e. Styling Fillet or Tri-tangent Fillet features.
If the corner type Ball is selected, the input boxes Fillet 1 to Fillet 3 are displayed. For each box only one existing Advanced Fillet feature can be selected.
The Support option is not available.
