"Invalid shape name ?Edge6" in sketch when completely different external geometry edge edge was referenced about freecad

[nazar-pc]

Another issue of a similar nature (I think) Core.zip

Everything looks great and was great before closing and reopening. Now if I open IoShieldBase sketch and close it, IoShieldPanel that references its point breaks with following:

03:10:10  <PropertyLinks> PropertyLinks.cpp(453): Core#Sketch006.Support missing element reference Core#Sketch005 ;g34847v1;SKT.Vertex1
03:10:10  <PropertyLinks> PropertyLinks.cpp(453): Core#Sketch006.ExternalGeometry missing element reference Core#Sketch005 ;g34847v2;SKT.Vertex2
03:10:10  Invalid shape name ?Vertex2
Clear constraints to external geometry

@bgbsww FYI
Is this a duplicate of #14563

[nazar-pc]

To be clear the app doesn't crash, it just results in errors and sketch no longer being fully constrained

[nazar-pc]

Happens on all sketches with Map Mode: Translate. Sketched that have Map Mode: Deactivated are not affected.

I just noted the same problem, but it happens even if the Map Mode is deactivated.

In the appended file, sketch001 is constrained by references in Sketch. If one tries to edit Sketch, the references are lost. Map Mode of Sketch and Sketch001 are deactivated.

Okay, I don't think FreeCAD is usable for me until this is fixed. So many things fall apart all the time due to this.

The FreeCAD version you test is a WIP. Last stable is 0.21.2 and FreeCAD is fully usable at this state as long as you take care of the TNP.

Hello everybody,

As for me, I am back to 0.21.2.

How do we know that this issue of 0.22dev is solved ?

When this issue will be closed.

Of course, I'm aware, makes perfect sense. TNP is something that seems to inevitably pop up in larger projects and this is why I wanted to test and report issues that I found. I intend to have a lot of dependant objects in a larger hobby open source project, hence trying to use this version of FreeCAD specifically or else I'll pull my hair out when need to make changes 🙂

The bug report is appreciated, and is under active work. We just don't want anyone getting themselves in trouble because they relied on a dev version :) Thanks again!

For the record, any name that starts with a ? is because we tried to look it up, and it wasn't there - ?Edge6 means we looked for the external reference and could not find a 6th edge in the geometry of the sketch at the time we looked.

One way to cause this is to delete geometry; and sometimes for us to fail to adjust the pointers to where the geometry went. There may be other ways to trigger this, and we'll see if this is one of those.
