Sheet metal bend limitations

[Anonymous]

I have run up against what I think is a resolution problem.

Now nobody laugh at what I'm trying to do - I need to do this for very good
reasons .

I have a sheet metal part .001" thick and I'm trying to place a bend in it
using a bend-line. I can bend it 2 degrees without a problem, but when I
get down to 1 degree or less I get errors:

"Could not build this fold... Modeling failure while merging the results of
face-face intersection."

. Has anyone tried things this small before? I need the bend to
be 0.4 degrees - yes, that's right 🙂

Cant you just put it over your knee and give it a whack?

Sorry couldn't resist.

It appears to be a little bit sensitive to the bend radius. What radius are
you using?

Also I was able to make one .4 degree by making it from two disjointed
faces... the second one on a angular plane and then using the Bend tool to
join them. I am presuming you are trying with the fold feature?

Can't make it disjointed - it's a weird shaped pattern that I imported from
Acad.
I tried small and large radii - .001 to .020.

Try .2 bend radius... works for me 8^) Is .02 the max you could use??

Actually I got it working with .02 bend radius also. But it is probably
more dependant on the edges, and you say it is a weird shape?

I played with this a little bit, and I ran into the same problems. It looks
like we are running into problems with the small surfaces that are created
for the bend zone. I was able to get close to what you need by initially
creating the bend at 2 degrees and .015 bend radius. I could then reduce the
bend angle to .4 degrees and then the bend radius to .005. It seems that it
is easier to reduce existing surfaces than to create them from scratch.
