I'm working on my roller-bearing. Tweaking physical parameters based on first 3D prints.

I wish I could have on-screen visibility and scrollability of VarSet, when I'm working on the 3D view, Sketches, solids etc.

I keep forgetting my variable logic in VarSets. Cognitive load is substantial.

Then I resort to copy pasting expression values between constraints.

This is my first major project (2nd part). Still learning best strategies, while also hoping for better UX to help #FreeCAD

As I swapped out the winter tyres for summer ones today, I checked out the hubcaps I made last fall and they all were in perfect shape.

I replaced my pinball hauling vehicle last fall and I had gotten used to the Volkswagen T5's minimalistic hub caps. Ford Transit had had those at some point but all that was sold these days was beaten up ones for very high price on eBay.

So I recreated the hubcaps in FreeCAD and printed them out of ASA. They're soft enough to snap on without violence, but they also stick on just as well as the Volkswagen version. I stole the wheel bolt attaching design from them.

So I'm doing a bearing. Have 2-part cage, with common Bodies, inherited with SubShapeBinder, (which also needs to be made solid with Boolean Fuse ok).

HOWEVER, the #SubShapeBinder is not freely editable: it needs to be created/inserted at the tip of the Body hierarchy.

Result: child Bodies cannot be updated, alas, because the topology breaks 😢

WORKAROUND

Create dedicated minimal Bodies for SubShapeBinder+Boolean Fuse only stuff. This eases their recreation on change.

What if #FreeCAD had:

In Sketch right-clickable "copy expression"?

That would reduce click path a lot.

Software development is a social activityHuK (@HuK@sw-development-is.social)I wish #FreeCAD had: Shorter click paths: – expression editor straight up, not behind = – more complete & consistent mnemonics (OK button not consistently alt-O-able) – PERHAPS some kind of floating clickable "recent expressions" window, enabling pasting expressions OMG: VarSets should be like code of text: editable, refactorable, viewable from multiple positions – not a cumbersome table *worm can* Should it be like a programming/scripting language? #FreeCADux https://sw-development-is.social/@HuK/114251142965023927

.. Or perhaps there already is a way to do this in FreeCAD?

Dunno python console for example...

But as VarSet is a new thing, this is my two cents at this point of my #FreeCAD journey:

#FreeCADux

Software development is a social activityHuK (@HuK@sw-development-is.social)This is my current workflow I've gravitated to, due to what #FreeCADux imposes to my #cognition: – copy-paste VarSet expressions FROM elements (Sketches, Paddings, Pockets etc.) to other elements – INSTEAD of recalling VarSet variable names FROM MY MEMORY. It's hard to recall them, yet I wrote them myself! No refactoring options. No support like in programming, where source code is LINEAR TEXT and TEXT EDITOR gives multiple views to it! I wish.... 1/2 #FreeCAD cf. https://sw-development-is.social/@HuK/114241166410763047
