Round a face

Description: 5 minutes; Lab exercise: 20 minutes

Create a chain of blend-like faces in order to tangentially connect two face parts sets.

Round a face, or Face Round, is new functionality with OneSpace Designer Modeling 2005.  The standard blend functionality in Modify 3D works with solids only and depends on the edges between faces.

Lab exercise

Work with Face Round - a new function in the Surfacing menu.

Prerequisites

Round a face

  1. Click Surfacing .
  2. Load round_face.pkg.
  3. Click Round in the Create Face section.
  4. Type /round_face as a name for the part.
  5. Click a point on the first face (Face 1).
  6. Click a point on the second face (Face 2).  The system will calculate an initial radius based on the position of the picked points and the face normals at those picked points.

  1. Use the 3D CoPilot arrows to change the radius of the face to 8. You can also choose a value from the drop-down list next to Radius.
  2. Click Extend to create a chain of faces with edges tangent to the initial face.  Use Stop Edges to stop the chain before the end of the tangent edge.

Imprint will imprint the face onto the original part.

  1. Click to complete the operation.  The boundary edges of the face chain are imprinted on the original part.
  2. Click Round in the Create Face section. Proceed with creating faces around the rest of the part.
  1. After selecting Face 1 and Face 2, open the Advanced Options menu and select the type of convexity you want in order to change the shape of the face chain. The initial convexity of the face chain depends on the initial pick positions on the two faces. Auto is the default.

Convex

Concave

 

  1. Continue creating face chains.
  2. Delete unwanted faces in the original part.  
  3. Gather to integrate new faces into the model.
  4. If you want to generate a solid part, use Grow or one of the other Surfacing tools to close any remaining gaps.
