All,
I am trying to create a rolled sheetmetal part in SW2005. I am having difficulty getting this to work. I viewed thread559-83712 and have not found this to help much. I have started by drawing the bent profile first, then I did a Base-Flange on that sketck. That worked, but when I try and view the flat pattern it is still the formed shape. ANy help would be greatly appreciated.

Can you post an image (faq559-1100) or the actual file (faq559-1177) for review?

Is the Base-Flange1 between the Sheet-Metal1 and the suppressed Flat-Pattern1 features in the tree?

Are you sure that your flat pattern isn't supressed?

I had no problem creating a part in the manner you described. Here's what I did:
Start a new sketch and draw an arc.
Create a base-flange, choosing material thickness and the length of the flange.
Create.
Select Flat-pattern...no worries.

???? The Flat-Pattern is supposed to be suppressed ... in the formed part anyway. The Flatten tool unsuppresses it. If you accidentally suppress it when in the Flatten mode, SW automatically reverts to the formed mode.

I know that. I didn't clarify properly. I've opened up sheetmetal parts in the past and tried to flatten them but the flatten-<BaseBend1> (under Flat-Pattern)has been surpressed. Don't ask me how or why...but that's what I was getting at.
Beyond that, it should have worked as btcoutermash stated.

Thanks guys! I was forgeting about adding the thickness and using a single line in the sketch...

I'm still trying to fathom out your solution to the first one.
"I was forgeting about adding the thickness and using a single line in the sketch..." ?????

Please post image WITH Feature Manager tree included, or better still the actual file.

Create the base flange the way you (I) did for the first part. You'll then want to unfold the part, not flatten. create your cut then fold it. You can find both of those buttons on your sheetmetal toolbar.

"Start a new sketch and draw an arc.

I was trying to use a closed profile then extrude instead of using a single line as the profile, then in the base flange command adding the thickness.

Issue 2 is that the part I have is only a stp model. It was created in inventor, and SW does not do that good of a job with feature recognition. We are trying to recreate this part so we have a good SW part and print.

Would you like to see the stp??

I really do appreciate it.

For that simple a part it would be quicker to recreate the model using JMirisolas method posted above. (@ 8:40)

btcoutermash,
after creating the base flange, you need to unfold the part, not flatten it. Next to the flatten button, on your sheetmetal toolbar, you should see two other buttons. One is 'Fold', the other 'Unfold'. Use these to creat your cut.

Ok, scratch my previous post, it won't work in that manner. What will work is this:
Create the flat first using the supplied dimensions. Insert a sketched bend vertically at the center of the center of the part. However, the radius called out on the sheet is too large. The largest radius that I could get to work is 4.66 inches.

I can't access it right now, but I'll take a look at it in a while.
Off topic here, but I went to high school with an Eva Coutermash...not a common name.

One different way of solving this is to draw the part in its flat state. Then, instead of using sheet metal commands, you could use the Flex, Bend command. Works nicely. You can either specify the bend radius, or the angle that you want to bend a specified length of material. It will also allow you to start and stop a bend a certain distance from the ends of your part.
