Advanced Features in Pro/E

• Sweep and Blend

Review of creating basic features

• Steps of constructing basic features.
• Define the material protruding direction, path
  or trajectory. (straight ling, circle, etc.)?
  Generalized dimension. ? DOF1.
• Define a cross-section for the feature. (with
  dimensions). ? 2D sketching.
• Define depth along the path of the feature.
  (depth, angle, etc.) ? 3D solid Object.

3
General ideas of creating features

• The cross-section of a feature is usually
  perpendicular to extending direction, path or
  trajectory. ? Find the most proper cross-section
  (2D) and appropriate path (1D). ? 3D feature.
• Good for protrusion, cut, hole, round, chamfer,
  etc.
• The idea is to make a feature fully constrained
  in the 3D space.

4
Protrusion and Cut

• Extrude (and hole)
• Path ? normal to the sketch plane.?Line.(1D)
• Sketch ? specify cross-section (2D)
• Revolve (and hole)
• Path ? normal to the sketch. ? Circle. (1D)
• Sketch ? specify cross-section (2D)
• Fully constrained in space.

5
Round and Chamfer

• Path ? pick the edges. (1D)
• Cross-section ? radius or definitions. (2D)

6
Conclusion of basic features

• Find an appropriate cross-section along a
  specified path. ? observation
• Pick a suitable feature type in pro/E to create
  one. ? analysis
• Pick proper references. ? sketching plane,
  orientation, dimensioning.

7
Advanced features I ? Sweep

• Generalized protruding path trajectory.(1D)
• Open trajectory.
• Closed trajectory.
• Cross-section (2D)
• Closed cross-section.
• Open cross-section with closed trajectory.

8
Advanced features II ? Blend

• Parallel
• Direction ? normal to sketch plane. (1D)
• Sketch ? different layers. (2D for each layer.)
• Rotational
• Sketch ? different layers. (2D for each layer.)
• Rotation angle ? normal to current sketch.(1D)
• Blend vertex ? control points for Blend
