**Short description of error**
This model was created with Blender 2.79 and then imported later in the new versions, to be used as a library, I noticed the problem because the add-on to export to glTF reports an error and cannot export, after a careful research I realized that the problem was due to this model which contains vertices with a NaN float value, ranges from 220 to 296 - from 2687 to 3094 from 3464 to 3592 from 12272 to 12811 13424 to 13693.
Could you find a way to fix this error?
