At scale, use weight and supply 1 or 2 extra. This is how pretty much every IKEA, LEGO, etc works with very small, cheap parts. End users benefit because it's easy to drop/lose/break one.

How does this work without dispensing onto the scale one by one? Just shaking them out of a hopper?

Yes it's by weight when you need exactly 20k tiny screws in a box. But when you need six that won't save you any time.

Then just use a small cup to scoop out some screws.

I mean I'll be honest, it's still a car crash of a program, but at least it's now a usable car crash. I've found the following workflow to be pretty good, using the part design workbench: - create a part - create a body - create a sketch - pad/pocket/revolve/etc - repeat with additional sketches to taste I've also been using the proxy object thing, I forget the name, the button is a green blob, to "import" geometry f…

Lots of it is single-threaded, which is an endless frustration on a machine with umpteen cores. Especially frustrating given that it means compute happens on the UI thread.

> the (OnShape) free tier is hobbled beyond the point of usefulness. The free tier is identical to the standard tier except you can not create private documents and it has a no commercial use clause. This has been the case for many years, so I'm not sure where "hobbled beyond the point of usefulness" is coming from.

This is a commercial use, isn't it? Might be clumsily worded, but it's out of the running for that reason alone.

You're weighing the bag. Dispense a load in and divide the total weight by the unit weight and you know how many you've put in.

Easier with heavy objects, and needs the variation on weight to be low for the number of items you're dispensing.

In volume, small parts are dispensed by carefully designed machines, and then the result is counted by weight. You still need control of the dispensing, and as he's putting in small numbers of items the counting is the easy bit.

The splash screen can be disabled and it takes 3 seconds to start on my mac. Fusion however has two splash screens (first a regular one, then one that covers the whole app window) and it takes 32 seconds to load! (to be fair, once loaded it's much better than FreeCAD).

Oh yeah, you won't find me defending Fusion. I can understand when you're loading a heavy scene or recomputing _everything_ in a complicated model, but I can't understand multi-second loading times and splash screens for loading...the start screen.

So that explains why the smallest parts often have spares in ikea and lego builds. Is this done because of the error in weighing the smallest parts, so they have a margin for error by allowing for an extra 1 or 2?

> Is this done because of the error in weighing the smallest parts, so they have a margin for error by allowing for an extra 1 or 2? This is a secondary benefit, the primary benefit is if the end user loses/breaks one. That part very well could be show stopper (Ikea 110630 anyone?). Now the end user is stuck - has to call, you have to ship, do you charge? do you give for free? they have to wait. they're annoyed, you'…

Being aware of this, I am waiting for a solution to what to do with the leftovers besides chuck them into a landfill. The problem, of course, is scale. No one is mailing 3 screws and an Allen wrench anywhere. Maybe once you hit 5 pounds of spare Lego . . .

If you have an IKEA store they do have a place for spares, and you can return them there. Assuming you go back from time to time.

For stuff bought online, e.g. Amazon, not much you can do.
