Laser Joint updated to V4.0: Fixed width pins, corner overcut fillets, and pin fillets!

lemon1324lemon1324 Member, Developers Posts: 107 EDU

Direct link to the new version here.

Instead of calculating equal pin/gap dimensions, there is now an option to define a specific pin width.  This option is only available when in the single joint operation mode.

In addition to the option to chamfer convex pin edges to aid insertion, these features can now alternatively be fillets.

There is a new option to fillet sharp corners created by corner overcuts.

(features as suggested by @marcus_jonsson, @brucebartlett)

As always, no bugs found on my test cases, but if you find any, send me a link to a public document with a minimum example demonstrating the problem and I'll look into it as I get time.

I still haven't had time to look into adding sheet metal compatibility.

    Would you be able to use sheet metal compatibility by using the BooleanBodies() feature because it is compatible with sheet metal?

    I think sheetMetalTab feature will be helpful in adapting this functionality for sheet metal use.

    Thank you @lemon1324
    I did find one bug, think it did exist in previous versions also. Pin face offset feature also offsets all other existing holes in the parts.

    To replicate: Extrude a 10 mm hole in a part, use laser joint on the part with 1 mm pin face offset. The hole is now 12 mm.

    I find the sheet metal tab works with ease for adding these style clip in tabs but miss the auto features for sizing and corners treatments.

    @marcus_jonsson, just pushed V4.1 which should fix that issue.

    @mbartlett21 yeah, I don't imagine that part would be too bad, since most of it uses booleans anyway.  It's mostly that I haven't done any sheet metal scripting yet, and there's a lot of refactoring from opBoolean to booleanBodies that would need to happen.  I'm sure sheetMetalTab would be helpful as well, but depending on how sketch-tab-pattern compares to the current primitive-pattern-boolean, that might mean a performance hit.

    I'm more concerned with the fact that a core assumption of the feature is that both parts are planar, and I assume the joint axis is given by the cross product of the largest face's normal from either part.  I also assume that once I've found a joint axis, all joints between those two parts occur along the same axis.  Neither of these assumptions are likely to be true with sheet metal parts, since the whole point of making it a sheet metal part is to add bends. 

    I'm not sure when I'll have time to really dig into figuring out how to refactor everything to keep current functionality while adding sheet metal, the last version and bugfix have been pretty easy since they were nearly already there in terms of existing code.

    I think it would be better to only boolean the bodies at the end because, each time you do something to a sheet metal model, it recalculates the flat pattern.

    @lemon1324, thank you for the amazing tool that this feature is!

    I'm using it in my project https://cad.onshape.com/documents/d00ceaba15e3ae5795e20cc8/w/ae8f127e4624154d6ac645ae/e/df3660a165963528ba859614

    But It seems that the solids created from the feature have some fault -- when I try to union them (to feed the model to simulator) - I get the error https://forum.onshape.com/discussion/comment/37106#Comment_37106
