Bend sheet plate (to known diameter)


New member
Hello all,

I have flat plate where I should draw holes and after holes are done I have to bend it to an arc shape with radius of 154mm. How it can be done?
I have attached an image with drawing in AutoCAD. How I can make this in 3D using CATIA?

Sorry, but I don't have access to CATIA right now and can't verify all the exact steps.

If you know how to use the Sheetmetal workbench, the process is fairly simple:
1. define the curved plate
2. unfold (flatten) the part, and add the holes
3. fold the part (with the holes) back to it's curved shape

If you're new to CATIA, I suggest you get some training.

OK Intogtar, here's the exact steps: (based on CATIA V5, R18)

1. Use the Generative Sheetmetal workbench (SMD license), and start by using the SheetMetal Parameters to define wall thickness and other material properties

2. Create a Sketch of the side profile of the the curved plate, with bend radius and enclosed angles

3. INSERT + ROLLED WALLS + ROLLED WALL, select profile sketch, and speciafy the length of plate

4. INSERT + VIEWS + FOLD/UNFOLD to see flat, developed shape

5. With unfolded (flat) shape;
5a. create a sketch of the hole
5b. INSERT + CUTTING + CUT OUT, and select sketch of the hole
5c. INSERT + VIEWS + FOLD/UNFOLD to see curved plate with deformed hole

repeat for more holes

6. With folded (curved) shape;
6a. create a sketch of a another hole
6b. INSERT + CUTTING + CUT OUT, and select sketch of hole
6c. INSERT + VIEWS + FOLD/UNFOLD to see flat plate with this hole developed in flat

7. to make a drawing view of the developed (unfolded) plate, use the UNFOLDED VIEW tool in the Drafting workbench and add dimensions

Notes on my last post:

1. The icons can be also be used for the all the steps. I listed the INSERT menu commands because they are easier to type in a posting like this.

2. I used CUTOUTS and sketches to define the round holes. The HOLE command can also be used.

3. I used the Generative SheetMetal workbench (not the Part Design Workbench) to build the solid model. Note the different features in the tree, and also the different set of icon commands:

I tried to identify each feature with a different color, but it's difficult to see - sorry

4. This part could be done with other CATIA methods - I think this was the quickest and easiest.

5. I found out there is a limit of 5 images that can be inserted in these posts.
