When I flatten my sheet metal part, a spike of sheet metal shoots out of the top of the part. Does anyone have a fix for this?
I am not able to screenshot the model on this pc but the issue is in your sketch for your tab feature. One of the short edges that creates the feature is less than 2 degrees off of vertical. When you unbend it, this edge is extended for whatever reason to meet the vertical edge on the opposite side of the cutout.
Someone else will probably post a model shortly showing this as well. The solution is to make the short line shown below vertical.
Can you post your model?
Here's the model.
That fixed it, Thank you! That was a good find.
I eliminated the tab feature and edited the sketch of Edge-Flange4, you might want to adjust the sketch a bit more but it eliminates that spike.
I don't use that tab feature so I couldn't comment on that, might be worth contacting your VAR as it might be a bug.
Wow Colton, that is random, never seen that before.
Like Peter said it would be useful to see the actual model if you can share it. Have you checked you bend allowances?
This does not answer the question to your issue... but take a look at this modeling method (convert to sheet metal) for sheet metal parts with multiple bend angels
I found a way to fix it, but I still don't know why the problem was happening in the first place. On the bend with the problem, under flange position, I was using "bend outside" but if I switch that to "material outside" it fixes itself. I wanted it to be bend outside, but this will work too.
Hi Colton, the problem is corner treatment !!
Expand the flat pattern folder, click the Flat Pattern feature and edit the feature. Deselect 'Corner treatment' under 'Corner options' - see above.
No more spike !!
Sorry, slow with my reply.
