How to interpret error message

[pridbor]

I don't think that i have ever used the "Check Part" tool, so when I got this error message I got a bit confused, it happens

I would have hoped that when I clicked on the "Edge" in the problem Topology, I would see something like a blue marking in the model where the proble was detected.

Could somebody please advice me as to how to make use of this function?

Thanks

I'll try,

The resulting 3D model is internally represented by those topology types.
The result from a feature or a change somewhere has caused Edge 2408 and 2405 to fall below a quality threshold. This can create problems if other geometry referencing those edges or faces formed by those edges are used in a new part feature or changes are made earlier on the design tree.

You can search the edges collection for 2408 and 2405, then look for the feature that resulted in those edges being created. See my example, CutFeature created the edge but the actual edge number changed because edges, faces and vertices are collections that update every time a part feature modifies the model geometry. Failed topology types can be false positives.

Exposing topology is not common in 3D CAD programs, but Alibre's feature error status messages include topology and language directly from the CAD kernel. To resolve failed features I refer to check part.

AlibreX chm help has a section on topology worth reading.

Check part is a heath check, it doesn't actually help you fix anything.

"AlibreX chm help has a section on topology worth reading."

I would like to, but I have no clue where to look for it.

Thanks

I forgot to add that there's not a one to one relationship between part feature failures and topology failures. A failed feature doesn’t necessarily create a failed topology type.

If working with an import, use Check Part & Import Advisor together - Import Advisor will suggest alternative import options which might get around the problems Check Part finds.

STEP, SAT and IGES give the best import advisor to check part topology results In my limited experience. import advisor shouldn’t exist. The import process should be smart enough to produce the best result.

It's all within Alibre, with no imports.

I fail to observe any problems with my model, so I will ignore it, counter to my normal mode of operation
