Re: Secret 2 way Pattern Part Performance Boost.
This is because for 2nd direction, there are 15*15-1=224 Boolean adds, and for the 2 patterns there are 14+14=28 Boolean adds.

Secret 2 way Pattern Part Performance Boost.
The secret is to not use 2nd direction for part patterning. Use 2 pattern features instead for a lot of objects. This was a 15x15 pattern. I was playing around with tile floor pattern for @jeff_mcaffer and noticed a huge performance hit when clicking on 2nd direction in part pattern function. It might be tied just to the add option of the pattern feature trying to join all the geometry. I have to try a few other things to explore and expand if necessary.

Re: Need some help with being efficient.
From where you are now, draw a box to represent the mating surface, and make it flush with the back. Then use the boolean>subtract tool, and subtract the holder from the mount. It will make slots in the negative shape of the tangs.
After you do that, move face on either the tang or the slot to make sliding clearance. Otherwise, the parts will never fit. I'll assume you are 3D printing this. If so, move face .015" as a start, and see how that fits when you make a test print of that localized area.
Re: Need some help with being efficient.
If efficiency is a goal, I'd say most of the features (mostly fillets) would be unnecessary if the method was approached differently.
The shape of the right-angled base piece, including the dovetail like rails, could be created with one sketch and one Extrude/Symmetrical. Another sketch on the proper face of that part to define the curved arm that goes toward that spindle and then an Extrude/Remove of portions of that sketch to create the shape. Lastly, another sketch and a Revolve to create the spindle.

Re: Part Studio
Removing a part by deleting it will always retain the sketches: Something else might be built on these, too! If you want to remove all of it, you'll need to start with the earliest element that was used to build the part (in most cases the sketch) and delete that. Then all other features built upon that will become invalid and turn red in the tree. Delete these, too. BUT BE AWARE that this will kill all other parts sharing the same features! That is why they are not deleted the usual way.
Re: Hole to Slot (new featurescript)
thanks @EvanReese. I figured it out. perhaps there's a smarter/quicker way, but this works:
in V9 drag selection multiple faces for one hole can be selected so drag selection is enabled
Re: New Video: Wood Rack Tour 🪵🪓
Good video!
I did a "Catio" in Onshape a while back but my model was definitely more "messy"!
Re: What tool to merge multiple small faces into a larger face at a defined offset distance
Awesome, I've got it up and working. That is a great tool. Thanks so much for sharing, it'll make my life way easier.
Re: Need some help with being efficient.
Regarding efficiency: Here is how you can do it in 6 features:

Technically you could do this part with two features if you use a custom feature. Well you could do it in one if it were made for this, but Intersect Views is a generic custom feature I made for things like making parts from old drawings that have a at least two drawing views.

Re: Render Studio Custom Appearances
You can now "import" appearances from another render studio. I've created a document in my "admin files" with some render studios where I import appearances for later re-use.
Not as "clean" as a real library system but it works reasonably well to save and retrieve appearances as you can a pick and chose which ones to import between studios.
