Sheet metal workbench questions on unfold and bend lines

I created a part using the sheet metal workbench. Fairly simple part, but for some reason I can't unfold the part. Never had this happen before, but its the first time I have done a sheet metal part in 0.18 version of FreeCAD, so I'm not sure if there is some incompatibility or something.

In any case, I have attached the model. Perhaps someone knows the trick.

What do you have selected that then enables the unfold icon in the tool bar?

Just an idea: Addons do not update automatically, you have to do it yourself via the Addonmanager.

Yes, once I selected the bottom of the box, the icon enabled, and it unfolded it. That was the trick. I figured it had to be something simple, but its been awhile since I did a sheet metal part.

Thanks.

I noticed in the picture you posted of the unfolded sheet metal, that you were getting the bend lines. When I do it, I am not getting the bend lines. I think I have something configured wrong, but playing around with the settings that pop up when I unfold yields nothing. No visible bend lines at all. Any clues?

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

I have a sheet metal project, and I created the Unfold for it, but the bend lines are not showing up, so I cannot do a 2D drawing for manufacturing it.

Is there some kind of setting, or something I am missing to get the bend lines to show up?

I have attached the model.
