Creating a Fillet Surface Using a Spine

You can create a fillet surface between two neighboring or intersecting surfaces using a spine curve as the fillet surface edge.

Before you begin: Open a 3D Shape containing two intersecting surfaces or neighboring surfaces with a common edge. You also need a curve running roughly along the intersection of the surfaces, or a surface edge.
  1. Select two surfaces and the spine curve.

    You can also select two sets of surfaces and a set of curves. Alternatively, you can use an automatically created spine curve.

  2. Click OmniFillet .
    A fillet surface is created by two lengths in the quadrant of the selected point positions.

  3. Optional: Click the invert normal handle to create the fillet surface in the quadrant to which the normals of the support surfaces are oriented.
  4. Change the continuity for Side A and Side B.
  5. Define the Length values for the start and the end of both sides. They determine the length between the spine and the radius runout lines (RRLs) where the fillet touches the base surface.
  6. Click to edit the variable length functions for both sides from the start to the end of the spine.
  7. In the Explicit Controls section, define the Tension values at the start and the end of both sides. They determine how much the surface is pulled toward the RRLs on each side.
  8. Click to edit the tension functions for both sides from the start to the end of the spine.
  9. Define the boundary condition of the weight function for tensions at the start and end of both sides. Select Free or Constant for Flow A and Flow B.
  10. Define the Parameterization of the fillet surface.
