During rounding, the edges that the round surface interacts with are processed in the following order:

• tangent/smooth edges

• sharp edges

The way in which the round interacts with the edge depends on the overflow option you specify in the Round Parameters dialog box. These options include:

• Roll Across Tangent Edges

  This option modifies the round to roll smoothly across any tangent edges it encounters.

  

• Cap Sharp Edges

  This option modifies the blend to roll along sharp edges, keeping the original edge intact.

  

• Roll Along Sharp Edges

  This option modifies the blend to roll along and notch any sharp edges it encounters.

  

• Force Roll Along at Blend Edges

  This option modifies the blend and forces it to roll along or keep the shape of the original edge.

  

• Miter at Corner

  This option modifies the blend and forces it to form a seam at any sharp corners it encounters.

  

• Roll Around Corner

  This option modifies the blend to roll around any sharp corners it encounters.
