Sheet metal help, am I being a bit thick?

Hi folks.

Not sure if I'm being a bit thick or if this is a bug.  (SM newbie I'm afraid.)

In the model below I'm close to what I'm after but the side flanges bend the wrong way, all 3 should have the same orientation.  However If I flip their direction the model fails.  I'm confused as I don't see how reversing the direction of the bend would change the geometry of the flat part?  How can one direction be good but the other bad?



If anyone is willing to give up their time to educate me I'd be grateful.

The issue is with the last feature named "Flange Sides"

As an aside these things cost £55 each in the UK.  If I can cut them in house onshape will have paid for itself providing we need at least 2 a month

Cheers,

Hi Owen, as a workaround, rather than use move face you can manually cut 2 bend reliefs before the first flange then use the shortened face to create the first flange.

This is a bug on our side. Will try to fix it for the next release. 
If you do your own corner relief, you can get the shape you want. See here. https://cad.onshape.com/documents/58a484bdbaa7e90f794b330b/w/cc7424e2fb320131e13b0327/e/a3c7094d0beea8b3a325d107

Thanks @NeilCooke that worked perfectly and is actually a nicer workflow to boot. Result

Woo-hoo.  Notification from the OS help department saying it was fixed, an update of the doc to latest version of Ons, supress the failing feature and rebuild and all is perfect.

Thanks helpful help dept.
