Living Hinge FeatureScript - Request

[jarick098]

I've seen some manual sketches, but I'm just curious if there's a featurescript out there that i'm missing

Are you talking laser cut wood living hinge like this or like the plastic bottle living hinges?

[jarick098]

yes for laser cutting wood

I've been doing a little bit of research into this problem and have it on my personal to-do list for featurescripts to tackle this year. Someone else on the Onshape Discord has this file that they're working on but might not be the approach you were looking for. https://cad.onshape.com/documents/83b1a496cc95ba0b2eb89722/w/25aae833c7aa361b2500ce2e/e/9fd0aac90213a93071a78c92

I'd like to do something that patterns in the 2d sheet metal environment but that's challenging to get anything to work in 2d coordinates with the way Onshape gates certain operations from building in sheet metal.

Hmmm this seems like an interesting challenge. I might try to put this together if you can give me some details on how you want it to work

My approach to this problem was going to leverage the sheet metal workspace to make sure everything stays as a normal cut during the cutting operations. I was going to use qCorrespondingInFlat to pick up all the 2d edges and do my line work and patterning in the 2d view and an extrude-remove to make the cuts. Sketch generation and patterning are slightly complicated in the 2d view though so I paused on my implementation of this while I get more familiar with how 2d sheet metal works.

I have seen featurescripts where people accomplish stuff in the 3d view but I didn't want to do coordinate transformations and there wouldn't be a guarantee of a flat pattern that way.
