How to Use Sweep in Creo

Open the part file

Launch Creo Parametric and open the desired part file from the file browser. The workspace displays the part environment with the model tree and common folders visible on the left.

Select the Sweep command

Go to the Model tab in the ribbon menu, then locate and click the Sweep command under the Shapes section. A tooltip appears explaining that this command creates three-dimensional geometry by sweeping a two-dimensional section along one or more trajectories.

Define the sketch plane

After selecting the Sweep command, a dialog prompts you to define the sketch plane. Choose the appropriate plane (for example, TOP-F2 (DATUM_F)) for your sweep path, then set the sketch orientation by selecting a reference (for example, RIGHT+F1 (DATUM PLANE)) and an orientation such as Right. Click Sketch to proceed.

Draw the sweep path (trajectory)

In the sketching environment, use the Spline tool to draw a curved path that will serve as the trajectory for the sweep. Adjust the spline as needed to define the desired path, then click OK to finish the path sketch.

Draw the section to sweep

Resume the Sweep command. The sweep command now uses the drawn spline as the trajectory. The path is highlighted, and you are prompted to define the section to sweep along this path.

Enter the sketching environment again to define the 2D section that will be swept along the path. For this example, draw a circle with a diameter of 44.72 units at the starting point of the path, and ensure it is properly constrained and positioned. Click OK to complete the section sketch.

Complete the sweep and generate the 3D solid. The software automatically generates a 3D solid by sweeping the circle along the spline path. The resulting solid is displayed in the modeling area, showing both the path and the swept geometry.

Review the final solid figure

Inspect the resulting 3D solid to ensure it matches the intended design. The solid figure is shown with the sweep path and section visible for reference.

By following these steps, you can convert a 2D section into a 3D solid along a custom path using the Sweep command in Creo Parametric.

Switch the sweep to a surface

After creating the sweep, ensure it is set as a surface rather than a solid. Click on the sweep feature in the model tree or graphics area and confirm it is displayed as a surface.

Apply the Thicken command

Select the Thicken command from the ribbon menu. This tool adds a uniform wall thickness to the selected surface, converting it into a solid pipe. Observe the default thickness value (for example, 3.05 units) displayed in the input box.

Set the desired thickness

Change the thickness value to 4 units by entering "4.00" in the thickness input box, and confirm the new value is applied to the surface.

Preview the thickened pipe

Use the preview function to visualize the effect of the applied thickness. Rotate and inspect the model to ensure the wall thickness is applied uniformly along the entire pipe.

Finalize the Thicken operation

Click the checkmark or confirm button to execute the Thicken command and create the final hollow pipe. The model updates to show the completed pipe with the specified wall thickness.

Review the final pipe geometry

Inspect the finished pipe from different angles to verify the wall thickness and overall shape, ensuring the geometry matches the intended design for piping applications.

Complete the process

The process is now complete. You have created a hollow pipe with a specified wall thickness using the Sweep and Thicken commands. Save your work and exit the modeling environment if finished.
