After I use "Delete Face", without heal, how do I add a surface that I removed?

[AmarD90]

In this part there are 2 flanges, kind of. I just removed one so that you can see but later I'll remove both. But I used "Delete Face" to get rid of it but it left a hole open where the flange used to be. How do I stitch that up so to speak so I can fold out the model? I tried using "Patch" and "Stitch" but it didn't do anything. 

I'm assuming this is the problem because when I go under "Sheet Metal" there is no fold out option. 

Any ideas?

You've got to try and use heal otherwise it creates a shell as you have now after that delete face.

[AmarD90]

I tried that but it removed to much of the part.

Delete that face first , then the rest. dxf attached

[AmarD90]

Did not quite understand what you did there. Did you first delete the flanges, like I did and then use heal? Or did you delete part of the flanges first?

[AmarD90]

No matter what I do I end up with a shell....

[salariua]

Delete that small face, with the transition radius first, then do the whole flange.

[AmarD90]

I'm sorry I don't want to be annoying but it doesn't work. I delete that small transitional radius first. Then I choose delete face again, with the heal option this time, and I choose the rest of the flange and I get an error message.

What is the defining feature of sheet metal?

Hint: (uniform thickness)

Also, you have a Contour Roll type feature in that part. (deformed)

...and, have you installed Service Pack 2 for 2014?

[AmarD90]

The thickness is 1,5 mm, which I have put in.

[salariua]

You need to get rid of that Contour Roll as JD poited out but you can't do it in one delete face operation. If you first remove that small transition face you can then do the rest of the roll.

See attached example.

Often, another solution is to Thicken only surface to faces that you want to retain.

Not sure why you used Derived Component - but in cases where I do use Derived Component I derive as a surface body rather than as a solid body and Thicken what I what to keep as the sheet metal part.

[AmarD90]

I used derived component because the part had screws and nuts attached to it, in on body.

I finally did it with the stitch thing. Now I see what I did wrong. When I used stitch I didn't select the whole body as well. Just the two missing surfaces so it didn't create anything. Thanks so much for the help!
