alt Hacker NewsTNP essentially cannot be definitively solved, as I understand it. Only extensively mitigated. Other CAD packages still have TNP issues.
FreeCAD had an additional problem that OpenCascade doesn't maintain any naming across its interfaces at all, which is what RealThunder's geometry naming scheme, that mainline FreeCAD now uses, largely solved. But his fork still has issues too.
Is DynamicData still properly supported in 1.x? Looks like it might be. Never really used it; I use a minimal mix of Spreadsheet (mostly for Configuration Tables) and VarSets.
As to problems: the main issue with FreeCAD as with all really complex packages is that it's impossible to diagnose a problem from a description that short; you pretty much always need the file to know what is actually causing the problem, because it's full of subtleties.
I will be posting a minimal example on the forums about this soon once I actually finish the project. Here [1] is the last issue that I had. The issue of getting the needed cutout on that forum post was one problem, but the much deeper issue was how a later operation broke the model in an unrecoverable way once it was removed. To me, that speaks to something deeply broken in FreeCAD's core use of Open Cascade, and I've noticed minor variations on this theme, like when undo operations sometimes don't really undo things and leave sketches broken. less common these days, but it's weird that it was ever a thing.

I used to use Spreadsheets but they just didn't scale, ie. every little addition and modification to the spreadsheet caused very slow global recalculations. DynamicData is a little better on this for some reason, but not much. I like the expression engine they use, but it's not good at only re-evaluating the dependencies that have changed. They should really be using FRP-like signals.
Anyway, I don't want to come across as too negative as FreeCAD is pretty good overall, but these tiny nuisances will continue to hold it back until they're sorted. It is looking better though.
