Changing a bend on a sheet metal part is probably the most common modification you’ll make. It’s quick and easy with a native part, but what happens if you need to change an imported part? With Creo 4, now it’s just as easy. Here’s how.
Just convert the imported 3D model into a Creo sheet metal part by defining a driving surface and you’re ready to go. See Convert a Solid Part into a Sheet Metal Part for details.
Now that you have a sheet metal part, just go to the Edit Bend command.
Click the Options tab to control the length of the wall when you edit a bend.
Constant leg length, which is the default, maintains the length as measured from the tangent bend edge with a fixed distance.
Constant wall height keeps the height of the wall constant, so the length of the wall is adjusted to keep the distance constant.
Constant flange length keeps the distance between the apex and the end of the wall fixed.
Constant flat length ensures that the length of the unfolded wall is not changed.
The system automatically detects bend reliefs and bend corners, and you can control how they should be treated.
Click the Adjacent Conditions tab to change these options.
For example, you can change the detected bend relief type to rip relief.
You can also select and change multiple bends in one step.
You will see the inner radius and angle of the two bends change at the same time.
You can see a brief demo of these tips in the video below.
