Creo Parametric 3.0 Basics - Part 3

Chapter 6: Sweep Features

The Sweep feature is one of the basic features available in Creo Parametric that allow you to generate a solid geometry. It can be used to create simple geometry as well as complex shapes. A sweep is composed of two items: a cross-section and a trajectory. The cross-section controls the shape of sweep while the trajectory controls its direction. For example, look at the angled cylinder shown in figure. This is created using a simple sweep with the circle as the profile and an angled line as the trajectory.

By the making the path a bit more complex, you can see that a sweep allows you to create the shape you would not be able to create using commands such as Extrude or Revolve.

The topics covered in this chapter are:

Creating sweep features

Avoiding errors and intersections

Various types of trajectories that can be used to create sweep features

Merging end faces of the sweep

Swept cutouts

The sweep feature requires two elements: a trajectory and cross section. The cross section defines the shape of the sweep along the trajectory. A trajectory is used to control the direction of the cross section and it can be a sketch or an edge.

To create a sweep, you must first create a trajectory.

Create a trajectory by drawing a sketch. It can be an open or closed sketch.

On the ribbon, click Model > Shapes > Sweep.

Select trajectory and click the Create or edit sweep section 3.jpg icon on the Dashboard.
