Fillet

Because solids share edges among faces, solid filleting is simpler and more powerful than surface filleting. You simply select edges of the solid and enter fillet radii. The surfaces are then blended across the edge and the faces are automatically trimmed. You can create constant radius fillets as shown on the left or variable radius fillets as shown on the right.

To create a fillet-edged solid:

  1. Select the solid in the Part View.
  2. Select Construct tab > Solids > Modifiers > Fillet to display the Edge Fillet dialog.
  3. Optionally enter a Name for the solid, or leave the default name.
  4. Select the fillet type from Constant or Variable.
    • If you selected Constant, enter the Radius.
    • If you selected Variable, enter the Begin radius and the End radius.
  5. If you want to fillet all the edges of a face, select it in the Face list, or click the Pick surface button and pick the face in the graphics window.
  6. If you want to set the radius for an edge, select it in the Edge list, or click the Pick curve button and pick the edge in the graphics window.
    7. Tip: Ctrl+click two edges to select all edges that make up the shortest path between them.
    Tip: Double-click an edge to select all tangential edges.
  7. Click the Add button to accept the face or edge and its radius/radii.

    The name of the edges and their fillet radii show in the Edge/Radius box and the edge is shown as a red arrow in the graphics window. For variable fillets, both the Begin radius and the End radius show in the Radius column and are comma-separated.

  8. Add any other edges you want to fillet. If you want to use a different radius on the next edge, enter a different Radius.
  9. Click Preview if you want to preview the fillet before committing to the changes.
  10. If you need to change the radius on an edge, select the edge in the Edge/Radius box, enter a new Radius, or Begin radius and End radius, and click the Set radius on selected button.
  11. If you want to change the radius of all the edges, enter the new radius and click the Set radius on all button.
  12. Click OK.

Controlling the shape of joint fillets

The joints where fillets intersect can either be mitered or blended.

To create a mitered fillet, fillet the adjacent edges in different fillets. The fillets are intersected and trimmed against each other:

To create a blended fillet, fillet the adjacent edges in a single fillet. The blend is calculated automatically based on the radii or the fillets:
