Need testers: TabGen (Fusion 360 Plug-in) improvements

Ok, now I was able to recreate it, and the first problem is because you are using imperial units, and I had a stupid bug.

The second problem is due to a rounding problem that I need to think through how to fix. It’s caused by switching back and forth from calculations within Fusion360 and within the plugin. I need to do all of the calculations in F360, but that’s giving me even stranger results.

Here is a bugfix for the imperial units issue. I’m still trying to figure out how to resolve the second issue.

0.51.001 is working the best to date, give me time, I’ll find something. :wink:

And here’s another bugfix that tries to minimize the chance of the rounding error that leaves the little sliver of material in the cuts.

I don’t think I can completely eliminate the possibility of that error occurring, but this version tries to set some more sensible defaults (depending on the units of measure) that should prevent it occurring; although, if you really want to, you can force the error.

And, yet another fix, to fix a couple of bugs I created with the switch to using F360 for the majority of the calculations.

Well, phooey.

One of my plans for keeping myself occupied while recovering from ankle surgery (again) was to learn F360 in time to help @markevans36301 find more ways to break your plugin. :stuck_out_tongue_winking_eye:

I’ve been going through @Secret_Sauce’s Fusion360 tutorials, and was all excited to get started, but my Mac App Store version of F360 kept yelling at me about not being supported any more, and I figured, heck, I’ve got plenty of time right now, might as well install the supported version…so of course now that I’ve wiped out the version that worked, the new one refuses to install, and I’ve got nothing to play with. sigh

I’ve posted on their support forum and am awaiting help…I hope it’s as responsive as ours!

I’ve had that problem before too. I had to completely delete the “~/Library/Application Support/Autodesk” folder from my user directory in order to reinstall the download version of Fusion 360.

Ohmygoodness, that did it! I had even downloaded and used their automatic deinstaller thingy to make sure I had deleted everything that needed deleting. Yay!!!

May be litteraly comparing apples to PCs but when I had F360 jam up cleaning every sign of it off and doing a clean install fixed it.

Yep, that’s what fixed it. Supposedly their “cleaner” app does that for you, but it didn’t!

@geek2nurse, so glad you got it fixed. That was FAST! Had you not already fixed it, I would have sent you instructions on what to do. Glad our Glowforge members are on top of things and respond even faster than I do.

TabGen v0.53-alpha is up, with a few bug fixes.

  • Fixed placement of fingers on the faces of bodies that have been tilted from the X, Y or Z axis.
  • Fixed a bug where failure to find a secondary face might cause the plugin to crash
  • Fixed a bug where the secondary face on tilted bodies might not be found, due to inequality of area caused by the precision of doubles used in the calculations. Face areas are now rounded to 3 decimal points and then compared to find matching faces.

TabGen v0.54-alpha fixs the ability to select a secondary face of a different length. The fingers that are created on the primary face will be copied to the secondary, but no fingers will be created or removed on that secondary face. See below for a couple of example screenshots.

One more update here for TabGen v0.55-alpha which adds initial support for defining the number of fingers to place on the face. In this case, the finger sizes will be calculated automatically. This has not been tested as much as the other two–automatic and constant width–finger types.

This will be the last update for at least the next week or so.

Love the plugin, but ran into a pretty nasty bug when working on a box. I’m not really sure what causes it, but here are the steps that reproduce it every time for me (v0.55).

Create a sketch on the x-z plane (top-down).
Make a rectangle with dimensions 4.855in, 5.56in
Add 2 right angle lines contained within the rectangle as if you were making the two walls of a box.
Give them distance of .25in from the sides of the rectangle (e.g. 1/4in material thickness).
Extrude one, then the other 5.56in creating 2 new bodies.
Hide one of the bodies, when attempting to use the plugin to make a finger joint on the vertical edge it will error “Error configuring parameter: body_1_1_default_width – abs(0.125in)”. With a traceback saying it failed creating a coincident constraint.

Thanks for the awesome bug report. I was able to track this down quickly. I’ll try to get a fix out later this evening.

See if this bugfix resolves your problem.

Can confirm that it fixes the problem. Thanks for the all the work on the plugin.
