2. Review of creating basic features
Steps of constructing basic features.
Define the material protruding direction, path or trajectory. (straight ling, circle, etc.) Generalized dimension.  DOF:1.
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. Advanced features in Pro/E
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)
Fully constrained in space.

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.

8. Advanced features II  Blend
Parallel
Direction  normal to sketch plane. (1D)
Sketch  different layers. (2D for each layer.)
Rotational
Rotation angle  normal to current sketch.(1D)
Blend vertex*  control points for Blend
