path stops outputting g-code

[xf3qc]

It would be interesting to see if the problem persists, if the model doesn't have the forbidden link:
Snip macro screenshot-ca9c97.png
To repair move sketch out of Body and delete Body.

This. Usually happens when I copy/move models/parts/sketches in between files back and forth... could that cause "forbidden links" ? But then, shouldn't the problem(forbidden link) persist even after restarting freecad?

I don't care very much how erroneous models behave, even if it is sometimes seemingly correct. If a faulty model can throw FreeCAD off track, then this is an error. And of course FreeCAD should help avoiding such models.

Did you try the fixed model? That may be more interesting than the consequences of editing a faulty one.

Can't recreate for now.
I never actually looked at/used a dependency graph
wouldn't know erroneous model from a proper one.

Will figure this out hopefully and report.

The Dependency Graph is not "magic", but it oftens shows errors as red connecting lines. If you see such a line, it usually means your model is broken in some manner. That does not mean you will automatically see a failure, but the model is definitely fragile at that point.

It can also be useful to see if you are following "best practices", but you need to know what those are in the first place. If you do, you probably will already be avoiding "bad practices."

there is goes again. Restarted. Works.

Did you have in the same FreeCAD session any other Path related error before?

Did you have in the same FreeCAD session any other Path related error before?

maybe yes, there is this other problem that is probably caused by my radical behavior so I didn't mention it yet.

there are 3 operations that have Base Geometry selected from:
square_style1_4hole_120mm Solid (which has a Placement of X: 240mm Y: 245mm)

if I change that placement to say: X: 227mm Y: 245mm

Path now fails with:
<Path.Area> Area.cpp(1318): project failed
<Path.Area> Area.cpp(1460): empty projection

But starts working again at other Placement coordinates (randomly).

Not sure if related

If you change the placement you may have to go into the job and adjust the stock too.

Tried that. Stock size is already whole table. Even if it was smaller, it would still work. It seems that the stock size specs only matter to height.
