unpredictable sheet metal bend allowance

unpredictable sheet metal bend allowance

unpredictable sheet metal bend allowance

(OP)
I found the sheetmetal bend allowance, which was defaulting to "K=0.5" has changed on a whole truck of my parts to "bend deduction=0"
I beleive this happened after I upgraded from 2010 to 2011 SP5.

My VAR doesn't seem to be able to tell me where this default is set, suggesting it is hard coded - SURELY they didn't change the hard coded default, particularly to bend deduction=0 which no material or tooling can actually create!

I use one template file which becomes a sheet metal file when I create sheet metal so the template doesn't currently have sheet any sheert metal parameters set in it - as far as I know.


I didn't do any setting files of my own because default settings were working just fine. Maybe I need to setup a bend table/bend note/guage toable files or something?

Can anyone explain this to me?

Currently I have someone looking through all the our sheet metal parts identifing which ones have "impossible" flat patterns.

If you are 100% sure that someone there didn't mess with your templates, I would have your VAR escalate the issue to SolidWorks. That, my friend, is bad juju.

RE: unpredictable sheet metal bend allowance

When you change the bend deduction/allowance/k-factor/etc in the sheet metal properties, SW remembers that setting for the next part you create from scratch. It sets that as your "default." It should not be changing this setting on parts previously modeled.
