Hi 

 

how do you develop this sheet by holding the folds? (allowing them to be recognized)

Hello Robert ,

If I understood correctly, you are trying to convert a surface with fillets into a solid (by providing the thickness). But when that is done, SC does not correctly convert it into sheet metal solid, and hence can not flatten it (Gives an error, "Sheet metal conversion error: Adjacent face is wall face"). Let me know if I understood it correctly.

Trial 1:

I tried the model you shared, recreated the same issue. Although when I tried identifying the form/feature   , it identified it as form instead of bend (refer to the image below). This identification is incorrect, and I am not clear about the reason. I will have to investigate it further to understand it.

 

Trial 2: 

I tried recreating this issue with a different model (please find attached video), where I did not face any issue. The only difference I can see is the fact that the model you started with itself has a curvature (R5.6m). Although I am not sure if that is the reason behind the false behavior, this will be my primary observation which I will be highlighting to the concerned people.

 

Regards.

Charudatta Bandgar Hi

I also tried to identify it as a form but it is not correct.

I look forward to your reply to find out how you can create this correctly unfolded piece.

In this file I circumvented the problem in the way indicated in the video , if you convert the file properly without doing this procedure would be convenient

 

Best Regards

Hello Robert ,

When you copy-pasted the surface at the end, and then pulled it, the previous curvature of 5.6 m, will not be there, it will be a straight component. Even at the end, when you pull it by 1470 mm, even that will be pulled in a straight line and it will not have the curvature as before and the problem simplifies to trial2.

 

Regards.

Hello Robert ,

 

I was able to replicate it with curved sheet metal as well, so the problem here might not be the one I am highlighting. Although I would convey it to the concerned people.

How can you ever expect a double curvature surface to be considered sheet-metal? - You won't be able to create it with sheet-metal tools?

Hello Michael Holm ,

Are you saying physically it will not be possible or in the SpaceClaim? 

I was able to do that in SC (for a curved sheet metal plate with a bend), but not with the component in the discussion.

[mh]

Charudatta Bandgar Yes, I'm saying that physically it will not be possible to produce the part with sheet-metal production methods.

Thanks, Michael Holm .

I am not much aware of the capabilities of the sheet metal bending production tools but thanks for highlighting.

Michael Holm Hi 

Is it possible to create it only with correct calendering?

Robert Well, I guess you can model it, but I doubt you can get SC to consider it a sheet metal part. Why would you, though? - From a production standpoint it's just a lasercut square - how you will create the waves, I don't know. Do you have someone to produce this for you? - What do they say?

Michael Holm Hi

I have a client who can do it with a calendering , vaves created during calendering

Best Regards
