Creating a Fillet Curve

You can create a fillet curve between two curves.

You can convert a fillet curve to a blend curve (Convert to Blend Type option).

Before you begin: Open a 3D Shape containing two topologically contiguous or intersecting curves.

  1. Select two curves.
  2. From the Surfacing section of the action bar, click OmniFillet .
    A fillet curve of the Radius type is created in the quadrant of the selected point positions.

    Tip: Activate the Control Points display in the Sculpt panel or by the mouse menu to visualize the continuity.
  3. Select the Fillet Type.
    OptionDescription
    RadiusDefines the fillet curve by the radius.
    Chord Length Defines the fillet curve by the chord length, that is the distance between both endpoints of the fillet curve lying on the support curves. The radius value changes accordingly.
    True Minimum RadiusDefines the fillet curve by a radius that is lower than the true minimum radius while keeping the continuities. The radius value reduces to keep G2 continuity.
  4. Click the direction handles to change the quadrant of the fillet curve.
  5. Drag the handles at the curve's endpoints to modify the radius or chord length.


  6. Drag the handle to modify Form Factor and Form Bias.

    You can also enter the required values in the panel or move the slider.

    The Form Factor determines whether the created entity is more flat or more copped. The continuity to the support entity remains unchanged.

    Form Factor 0.1 Form Factor 0.5 (default) Form Factor 0.9






    Form Bias is similar to Form Factor but the changes apply in an asymmetric way on each support. This allows you to create entities being closer to one of the two supports.

    Form Bias 0.1 Form Bias 0.5 (default) Form Bias 0.9






  7. Optional: You can click Go back to selection at any time to change the selection, define and use selection sets, or to choose another mode in the selector panel.
