Sections > Define

• There are three sections to be blended. Draw section 1. Note the

sections must have same number of sides. Also, pay attention to the

starting point and direction of the section.

• Select FDP as SP > Sketch > sketch a rectangle > OK

• You can sketch a square with the center at the CS origin by

sketching the square carefully.

• Enter the distance of the second section from the first.

Dimensions

• All sections are squares of size, 30, 50, and 100 whose centers

are aligned.

• Depth 1 and 2 are 40 and 50, each.

General Blend

• Select Front DP as sketch plane

• Accept the feature creation direction as is.

• Select Top DP as top reference plane.

• Sketch section1 and then place a rotation axis > Done Sketch

• Enter rotation angles about x,y,z-axes.

• Sketch section2 and then place a rotation axis.

• Continue? Yes > sketch section3 with a rotation axis.

• Continue > No.

• Enter the depths. Depth is the distance from the reference

coordinate to the next reference coordinate.

Dimensions

The centers of rotation are at same level.

Note that rotation is

done about local x,y,z-

axes in Pro/E.

Blend with Vertex

1. Create three sections as given above.

2. For the last section, use only three sides. One more side will be

given by blend vertex as:

Pick on a vertex (now highlighted), then, use RMB to bring up

the shortcut menu > Blend Vertex (or Sketch > Feature Tools >

Blend Vertex).

Blend with a Point and Different Cap Type

In these examples the last sections are made of a point. Only the

first and last section can have a zero-area, i.e., a point. For a

point section, sketch a point with

Sketch > Point > place a point

And then, place a reference coordinate. For parallel blend, the

point section automatically results in a sharp cap. For non-

parallel blend, once the last section is defined as a point, either

Sharp or Smooth cap can be specified by Cap Type after done

with sketch.
