Creating a Spinal Bend in Creo Parametric 10.0


In this TechTip, you’ll discover how to utilize the Spinal Bend feature in Creo Parametric 10.0. This feature allows you to bend a solid or quilt along a curved spline. Begin by choosing a curve that maintains C1 continuity (tangent), and then select the geometry you wish to bend.

Creation of Spinal Bend

Step 1:

Open the part file spanner.prt

Step 2 :

Select Spinal Bend command from the Engineering drop down menu of the Model tab.

Navigate to the Model tab’s Engineering drop-down menu and choose the Spinal Bend command. This action initiates a spinal bending operation, potentially impacting the 3D model’s structure or design.

Step 3 :

Go to Reference tab and select the Spine curve as shown.

Step 4 :

Reverse the spine direction by clicking on direction arrow as shown

Step 5:

Click on the Bend geometry collector and then select the model geometry as shown.

Step 6:

Observe that the model has been bent as per the selected spline curve.

Step 7:

Enable and then disable Preserve Length option in Settings pane and observe the changes in model

Note : This change in model happens because when Preserve Length option is enabled, the original length of the model will be maintained despite the model being bent. But when this option is disabled, the length of the bent model adjusts as per the length of the spline curve.

Step 8:

Observe the Unattached and Attached preview as shown.

Step 9:

Click OK to finish the Spinal Bend and observe the bent model.
