FreeCAD Collection of Confusing/Frustrating Errors

Datum 90.00 deg for the constraint with index 12 is invalid

What does this mean? Why am I not allowed to apply the 90 degree constraint in an obvious place?

[nelsonic]

"Datum 300.00 cm for the constraint with index 17 is invalid" ...

Sadly, the forum topic that matches this Google Search: https://www.google.com/search?q=datum+300+cm+for+the+constraint+with+index+17+is+invalid

https://forum.freecad.org/viewtopic.php?t=38206 just advises the OP to "solve the issues in the sketches" ... that's what I'm trying to do ... but FreeCAD won't let me!!

This looks promising: https://youtu.be/FaVLVg65gl8 🤞 FreeCAD "Datum xx mm for the constraint with index xx is invalid" fixed

[nelsonic]

"The solution to this error is to remove redundant constraints in your drawing ..."

That's great. But now I have to go and find the redundant constraints ... 🔍 Why can't FreeCAD highlight the conflicting constraint. And why the cryptic error message? 🤷‍♂️

The sketch has a lot constraints that I didn't input ... i.e: they were created by FreeCAD Automatically:

The only constraints that I applied (and want) are these last 4:

[nelsonic]

Tried disabling the constraints and adding the new length constraint:

No luck. 😢

[nelsonic]

made some progress:

But this is getting ahead of myself ... I still have to do all the lower layers. So will be deleting (undoing) this wall to do the drainage, insulation and slab first.

Reported a bug with Arch Wall: https://github.com/FreeCAD/FreeCAD/issues/9659 Related forum topic: https://forum.freecad.org/viewtopic.php?t=78586 (opened by me...) Let's see if we can get past this wall.

Sadly, when I restarted FreeCAD and try to find my model using Zoom "Fit all" it zooms out to Trillions of Meters:

This is immensely frustrating because it's a rogue object in the model that I cannot find! 🤦‍♂️

[nelsonic]

Sad panda ... 🐼 😢

[nelsonic]

Not responding ...

I've made decent progress with the model but every now and again the program hangs or crashes and I have to redo some of the work it's like MS Word or Photoshop in the 90's again ... 🙄

[nelsonic]

Each time I try to open the Spreadsheet view in FreeCAD it crashes ...

[nelsonic]

Faces in Shape of Base, return without a rebar shape for Rebar. 🤷‍♂️

[nelsonic]

Really sad about this one ...

Was making such great progress with the reinforcement ... 😢

[nelsonic]

Sad times ...

[nelsonic]

Null geometry in isBsplinePole - please report

🤷‍♂️

Trying to create a fairly basic sketch for the profile of the concrete slide: https://github.com/dwyl/workshop/issues/137 ⏳

[nelsonic]

This is my favourite one so far: 🤣

Suuuuuper helpful. 🎉

[nelsonic]

Another hour another crash ...

This is getting old. 😞

[nelsonic]

This was a fun one:

Turns out that the copy of the solid that Part Workbench made in order to allow me to make a new sketch was preventing me from doing a pad based on the sketch... 🙄 How on earth is a beginner meant to know this kind of stuff?!
