Sheet metal ring won't unfold.

[Anonymous]

I found multiple tutorials on how to do this on this support page, but they don't seem to work anymore. I used it once, in an unrelated file, and the screenshot is just of a test file that I made. I will warn you that I am a novice, I have only been using Fusion 360 for a couple of weeks, but I decided to download it to make some rings. I need to put text on the rings. No problem. Here is what the tutorials said to do, as I understood them

-Make a sketch of your ring including the thickness of the ring.

- Draw a radius line

-Draw another line, using the offset tool a small distance away from the radius

- Trim the outer circle between the lines

-Create a flange out of the trimmed, circular face

-Extrude it to your desired height. 

-Extrude the one of the faces of the cut section partway through the gap, using join so that it creates a small rectangular prism

-Go to modify (in the sheet metal work space) and click unfold bends.

-Select the outside face of the rectangular prism, and the outside, curved part of your ring as the bend. 

-Add your text as a sketch to that face

-Refold the ring, and extrude your text.

If you look at the attachment, I followed those steps until I got to the small rectangular prism that was extruded from the cut face. However, I can't select the rectangle as the stationary entity as I'm supposed to be able to, or select the outer, curved face as a "bend". As I mentioned, I have followed those exact steps in the past, and it worked great. I have no idea why I can't select the correct faces.

Thanks in advance for the answers.

Most likely reason is you probably did a Press/Pull instead of an Extrude. Note the difference between your image and the extrude operation in the screencast.

What are the links for the Tutorial references?

File>Export and then Attach your *.f3d file here and end all doubt.

Here is the f3d file. Thanks again. This is just a test file where I followed the steps that I described above exactly. Make two circles, trim a small bit out of your ring, try to make a flat fact to set as the stationary entity, and I can't select the flat face.

Sorry I didn't understand what you meant. I tried checking back to where the tutorial that I used was, but it looks like it got taken down for some reason. I can't find the same thread that was usually first in my results when I search "text on a ring fusion 360 ." Anyway, I'm sure that you could find a very similar tutorial if you just search what I did.

Perhaps because it was all wrong.

When I get a chance I will make a video on how to properly create this part (actually - I already made the video some months ago and posted it here, but now I have to locate it).

1. -Make a sketch of your ring including the thickness of the ring.
2. - Draw a radius line
3. -Draw another line, using the offset tool a small distance away from the radius
4. - Trim the outer circle between the lines
5. -Create a flange out of the trimmed, circular face
6. -Extrude it to your desired height. 
7. -Extrude the one of the faces of the cut section partway through the gap, using join so that it creates a small rectangular prism
8. -Go to modify (in the sheet metal work space) and click unfold bends.
9. -Select the outside face of the rectangular prism, and the outside, curved part of your ring as the bend. 
10. -Add your text as a sketch to that face
11. -Refold the ring, and extrude your text.

Step 6 is where the instructions are faulty.  In Step 3 create the flange with the distance set to the width of the ring (see my earlier screencast).

For me Step 1 is wrong.

[etfrench]

True

The thickness of the ring is set by the Sheet Metal rules.

Ohhhh. I think I know what I was doing wrong. When I want to decide the thickness of the ring, I have to use the sheet metal rules to do that, I can't just have two circles the width away. I have to select an edge not a face when I create a flange. If I'm wrong, thank you for bearing with me, and please tell me how I'm wrong. If I'm right, please tell me how to modify the sheet metal rules. I just want to make sure that I know how to set the thickness of the flange. Thank you all, you've been super helpful so far.

Step 1. Sketch desired profile (single edge - Sheet Metal Style will determine Thickness).

Step 2. Flange (see Attached *.f3d file).

THANK YOU ALL SO MUCH!!!! You've solved my ignorance of how the program works.
