Tips & Tricks: Creating Bend Reliefs in Creo 3.0

If you design sheet metal parts, you should know that Creo 3.0 now has a number of new options for working with complicated bends. We summarized these new capabilities in a previous post, but here’s a closer look at what happens when you create bend lines. In short, the system automatically creates reliefs for you.

A bend relief is a notch cut into the material when a bend is made close to an edge. Without it, the bend may create distortion or tearing.

Here’s all you need to know to take advantage this new option.

To create a bend, follow these steps:

  1. On the Model tab, in the Bends group, click Bend. This opens the Bend dashboard.
  2. Select an edge as a reference, and use the offset dragger to locate the bend line offset from that edge.
  3. Trim your bend line by dragging the handles at the ends, or manually enter a value for the end offset. The system automatically places the default reliefs at the ends of the bend line. Note that the default relief type is Rip for the sheet metal part templates that ship with the system.

The bend line on this part is offset 1.50 inches from the reference edge.

To change the type of relief, follow this step:

  1. In the Bend Tool dashboard, select the Relief tab, and then choose your preference from the Type drop-down menu. You can define your reliefs as No ReliefRipStretchRectangular, or Obround. Note that if you change the relief type to No Relief, the the system extends the bend to the end of the part.

Two tabs are bent and given reliefs on each side that extend beyond the bend line.
