6. Revolved ProtrusionsThe revolve option creates a feature by revolving the sketched section around a centerline from the sketching plane into the part.

A revolved feature can be created either entirely on one side of thesketching plane or symmetrically on both sides of the sketchingplane. The One Side and Both Sides options are available. If youchoose Both Sides, the feature will be revolved symmetrically ineach direction for one half of the angle specified in the REV TO menu.To create a revolve, we proceed in the following manner.

Feature=>Feat=>Create=>Solid=>Protrusion=>Revolve=>Done=>One Side=>Done=>Okay=>Default.

After creating a revolved section, select Done and the REV TO menuappears. This menu allows you to specify the value of the features’sangle of revolution. You can choose the Variable option for a userdefined angle of revolution, or you can choose from the four presetangles, 90, 180, 270 and 360.

7. Chamfers

Chamfers are created between abutting edges of two surfaces on theSolid model. An edge chamfer removes a flat section of material From a selected edge to create a beveled surface between the twoOriginal surfaces common to that edge. Figure below showsEdge chamfers.

There are four dimensioning schemes for edge chamfers, as described below:--

(1) 45*d Creates a chamfer that is at an angle of 45 degree toboth surfaces and a distance d from the edge along each

surface.The distance is the only dimension to appear when modified.45*d chamfers can only be created on a edge formed by inter-section of two perpendicular surfaces. Figure is below.

d

(2) d*d Creates a chamfer that is at a distance d from the edge alongeach surface. The distance is the only dimension to appear when modified. Figure is below.

(3) d1*d2 Creates a chamfer at a distance d1 from the selected edge along one surface and a distance d2 from the selected edge along the other surface. Both distances appear along their respective surfaces when modified.

(4) Ang*d Creates a chamfer at a distance d from the selected edgealong one adjacent surface at a specified angle to the surface. Figureis below.

To create an edge chamfer,1. Choose Chamfer from the SOLID menu.2. Choose Edge from the CHAMF menu.3. Choose 45*d or d*d or d1*d2 or Ang*d option.4. Enter the chamfer dimension.5. Select edges to chamfer.

To create a corner chamfer,1. Choose Chamfer from the SOLID menu.2. Choose Corner from the CHAMF menu.3. Pro/E displays the PICK/ENTER menu, which allows to specifythe location of the chamfer vertex on the highlighted edge. The PICK/ENTER menu options are as follows. Pick Point Pick a point on the highlighted edge to define the chamfer distance along the edge. Enter Input Type in a value for the chamfer distance along the highlighted edge.

4. Pick or enter values to describe the chamfer lengths along the edge.After selecting the first vertex Pro/E highlights the other edges, oneat a time, so that one can place the other two vertices.5. Select OK button in the dialog box.

8. Sweeps

A sweep is created by sketching or selecting a trajectory and thensketching a section to follow along it. A sweep is created in thefollowing manner.

9. Blends

A blended feature consists of a series of at least two planner sectionsthat are joined together at the edges with transitional surfaces to forma continuous feature. Two types of blends we will discuss. One is thestraight blend and the other is the smooth blend.

Blends (straight/smooth) are created in the following manner.

10. Helical Sweeps

A helical sweep is created by sweeping a section along a helicaltrajectory. The trajectory is defined by both the profile of thesurface of revolution (which defines the distance from the sectionorigin of the helical feature to its axis of revolution) and the pith (the distance between coils).

A helical sweep is created in the following manner.
