Re: No bend lines coming out on my unfold of a sheet metal project

hello
you do not have the right version of sheetmetal ; or
do you have to erase the sketch that contains the fold lines

This is what I have done:
- Updated to latest SheetMetal
- After Restart: open file and switch to SheetMetal WB
- select inner face of the bottom
- click the unfold icon
- leave all options as is (only checked Generate projection sketch with color blue and Manual K-factor, set to 0.5; transparency set to 70%)

I have the latest version of sheetmetal, its version 0.2.31

Why do you see a separate sketch. I just see the Unfold object, with nothing else. Is there something about visibility I have wrong in the workbench?

You get them if you have checked "Generate projection sketch".

The reason I started a new topic, was because my original problem was solved, and now I had a new problem with bend lines. By merging this with the old thread, the topic is no longer correct. I can unfold now, but I don't get the bend lines. So, your merging my topic with the old one, isn't really helpful to let people know what my problem is anymore.

Ok, sorry. Would it be enough to change the subject of the first post? It is at the same time the title of the whole topic.

Yes, I think that would be helpful.

From what I can see in the image you posted, not all the bend lines seem to be visible. This is beyond frustrating, as I have tried to even rebuild this several times. It just doesn't work for me.

My latest try was to not use the pad from the part design workbench on the initial sketch on the bottom of the box, and instead use the sheet metal workbench to create the bottom from the sketch. When I did the bends, then the bends where all dependent on each other, which seemed like the better approach. It still didn't work.

The reason this is important, is because I need to create a 2D drawing, using the TechDraw workbench, and show the measurements for all the bend lines.

I have attached my revised model, doing it all, including creating the bottom, through the sheet metal workbench.
