I have a friend that can't seem to get this cylinderical model to unroll correctly. Any help would be appreciated. Sheet metal isn't my first love.

Good morning Doug,
Works well here,
In what way are you saying it doesn't un-roll correctly.
When you flatten the cylinder, in the front plane it shows up skewed and all you need to do is select a face and go normal to, then hit the space bar to pop the view dialog box. Select the front plane and than make a new view or re-do the views.
Let me know if this is what you want and I put up some pics,

I guess what I should have included is that when it unrolls/unfolds. Some of the holes in the cylinder are missing in the flat view.
Good afternoon Doug,
Do you know the dimensions of the hole layouts in the flat pattern?
Or do you need to design the part in a rolled part?

Doug, It seems to unfold properly for me, SW 2011 SP4.0. I'm a bit confused on the Sheet Metal feature inserted before the base flange. I've never seen or done anything like that. I'll try to take a more in depth look at it as the day goes on.

Good morning Bernie,
I'm not sure when it started but, more people are doing the initial sketch and adding the sheet metal features right away, it might make some sense some of the time, but for me I may be too much old school on that as well. Most times I design the part then insert the sheet metal bends.
I think the big part is when you add your sheet metal in the first feature you can carry on with all of the sheet metal information, however for me it's useless till they change the bounding box information that I can automatically set it up in my Custom Property Tab Builder, oh well. It actually adds to the feature tree and makes you go back and edit the flange sketches if you have holes or additional cuts, etc..
Later,
John
Thanks John! I can always depend on a good explanation from you! I have done many rolled tubes and this one surprised me. Bernie
This is a normal, decent, quick way to start a part that doesn't have a flat face in order to add an edge flange. The method is to start with an open sketch and just make that the base flange. Also works well on a part that has a rolled face and then a flange. One sketch, make it the base flange and done.

Doug,
Change Cut-Extrude6 to a Normal cut and it appears to work properly. Not sure why 6 needs to be but 5 doesn't. But, should they all be normal cuts or is it that way on purpose?

Good afternoon Wayne,
Good one,
The holes that didn't show up for me were the Cut-Extrude8, I checked that feature, but I didn't think to go up higher,
Kind of weird.
Later,
John
Thanks Wayne,
I changed all of them for good measure. That solved it for me as well.
Cheers,
Doug
You might send that one in to see if they can discover why it fails without the normal cut on that one feature.
