[Feature Request] Sketch - Identify Geometry Index (inside and outside Edit Mode)

[paullee]

Thanks for updating

[paullee]

I will try merge the Link functionality first, and followed by the topo naming thing including the sketch export. Hopefully it can get into 0.19 in time.

I understand your branch tackled toponaming issue.

Not exactly same problem - In current sketcher implementation, if one edit primarily delete some edges, the edge indexes are 're-ordered', so 'link to external geometry ' to this sketch (link by its edge index) would fails / point to 'wrong' edges.

Wonder whether in your implementation, this is also resolved?

Thanks again.

Yes, it is solved. That is one of the fundamental requirement of a topo naming implementation. In my branch, both external and internal edges in a sketch has an additional integer ID that is unique within the owner sketch, and will not change. Other shapes extruded from the sketch will name their faces and edges based on those IDs, so they should be stable too. And various link properties will use the stable name automatically.

Thanks. Look forward to the improvements !

There is a discussion about Changing a line to a constructor confuses freecad

Sorry always pinging you as I am not sure which and if features in this discussion has been merged

Thanks

• The edge name referenced 'externally' is different from 'internal' (edit mode) so it change when some of the edges turned into construction mode
  Sketch - Identify Geometry Index (inside and outside Edit Mode)
• The edge name become different / reordered when some of the edges are deleted / added
  Sketch - Identify Geometry Index (inside and outside Edit Mode)

Thanks for the pointer

Related though not exactly the same, but should be very useful

The sketch edge naming is the first step I did for the topo naming feature. It hasn't been merged yet. Should come in 0.20.

The edge names do differ for 'edit mode' and 'shape mode'. But as long as the edge exists, you can always refer to the edge using its 'internal edit mode' name. The construction mode just toggles the visibility of that edge in 'shape mode', but the name stays the same regardless how many times it is toggled.

Thanks for the explanation !

The below feature seems resolved the original problem - I originally thought needs 'uniting' the 'internal/edit' mode edge and 'external/shape' mode, but seems below features works, not yet test though

Hi Realthunder. Following recent discussion understanding about ID in sketch, I am trying to get the info about the edge you advised inside and outside Edit Mode of sketch.

But it seem getSelectionEx() only return Edge name ( see screencaptures) - e.g. s.SubElementNames >>> ('Edge1',)
, but Selection panel show - ....Sketch;g11, SKT_Edge1

BTW, what g11 is about ?

Thanks for any idea.

Just stumbled upon this thread. This feature has been added to my branch when I implemented SketchExport, as you've already known. In my branch, the sketch elements are using the same name (but with different prefix for disambiguation) in and out of the edit mode. The ending integer (i.e. the 4 in ;SKT_g4) is the geometry ID, which is a new attribute (named ID) I added. You can match them (Sketch.Geometries) in a loop.
