2 Bend Settings Please?

markZCPTL — Tue, 04 Apr 2023 20:57:33 GMT

Hi All, I am hoping someone can help me with this. I am trying to do 2 bends on a piece of 0.55 sheet metal. However, whilst I can do all the other bends successfully, I cannot get the final bend to work. I dont know how to setup the 2 bend relief settings to get this to work. As you can see in the attached image, all the other folds are done, I simply need to fold the final fold to 90 degrees but I keep getting errors.

Please attach your model. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I am sorry John, I have been told I cannot share the file for commercial reasons.

You will need to add a relief to your sketch, that is a least as big as the bend tangents. The Bend tool does not do bend reliefs very well on its own.

Thank you Carl. To do that I will have to work through hundreds of files to add the reliefs. Our original files were drawn in AutoCAD LT and we use those file to laser cut prior to folding. All works well. However, I was trying to convert to Fusion 360 and "digitally" fold the items for training and development purposes. I was hoping to override the bend reliefs or at least turn them off so I could keep with the original files.

Then isolate the element or recreate the situation in a new file.

Thanks Gunther for your time in creating the video. I have tried this in the past to see where I have gone wrong with my previous approach however, with hundreds of drawing I will need to do from scratch it is going to take a long time. We will also have to text each new drawing to ensure they still work when laser cutting. I was hoping I could simply import the AutoCAD files and the "bend them" using the flange and bend tools. I was hoping I could simply change some settings in the sheet metal rules to achieve the bends, or, ignore the rules completely to allow the bend to happen. Do you know of a way to override or change the settings to fold the original sketch?

regards

Mark

I suppose after working with AutoCAD since version 2.1 (in the 80's) I just need to learn a new method of designing 🙂

thanks Mark

Hi,

What could be easier and faster than the process that can be followed in the timeline?

I agree, I have been "playing/testing" to change my approach. However, I have found when I export the flat pattern it is adding all the bend and bend extent lines, which will cause issues with the lasers. I have done some research and found you can turn off bend extents in drawings, you cannot turn off bend lines. Therefore saving as DXF file is adding in the bend lines. I tried a couple of approaches, but eventually found if I create a projected sketch on the flat pattern and save as dxf, this does not have the bend or bend extent lines 🙂

Again, Gunther, thank you for your help. It is much appreciated

Mark

@markZCPTL
I’ll just mention that bending from flat is all wrong. (Was bend allowance calculated the the flat?)

The customer pays for the finished dimensions- so design in finished form and let Fusion calculate the bend allowance (deduction).
