Cant unbend this part, seem like a no brainer

We are using SolidWorks 2003, and I cant seem to unbend this part.

If I delete the last feature I created, it will unbend. What am I
doing wrong?

I uplodad the part file here, any help would be appreciated. Thanks.

hmmm,

just tried it in sw2005 sp0 and it opened with errors, rolled thru the
creation and it is fine.

Maybe its a bug with SolidWorks 2003.

Your right, it won't. Can't see anything wrong, but I don't remember if the
SW2003 rules are different.

It does work correctly in both SW2004 SP4.2, and SW2005 SP0.1. (after a
cntrl-Q)

SWM,
I opened it in 2005, ctrl-Q, and the flat pattern works. Same for 2004.

Like the others said, it works after rollback and unroll.

Also, there are better ways to use the sheetmetal tools. Instead of doing
a bunch of cuts and extrudes, it would work out a lot better to just edit
the flange profile on an edge flange.

Matt, what do you mean edit the edge flange profile? The base flange
profile is an endview, which is extruded. I am making cuts on the side
view of that base extrude. How is this possible to do from the base
flange?

Please explain, I would like to know the "best practice" with doing
this. Thanks

If possible, could you post a sample part with what you are talking
about? Thanks.

 

I think the issue is that you told it that it was a sheet metal part, put in
the bends, and then added more material to it. SW2003 didn't like to do
that, but 2004 & 2005 handle it just fine.

Two other ways to do it.

1. If you start with what you have, delete the extension & just increase
the length of the base flange by the 3" that you extruded the tab. Then
readjust the cuts.

2. Start with the extrude, make your cuts, add the extension, and then tell
it that it's a sheet metal part by inserting bends. It will then pick up
the complete part and flatten it with no problem.

By the way - interesting part. It looks like the side of the shoe in a
combine.
