Mesh - visibility problem

[MichaelT_123]

Hi Fellows,

I have STL 2D mesh in ASCII format ... generated by an engineering application. It shows itself correctly in many STL rendering apps like MeshMixer, MeshLab, etc. ... and even as an avatar in the designs side panel!
Strangely enough, it's wireframe is invisible in F360, although its mesh data is accessible via API without any trouble and shows sensible values (nodeCount=620, triangleCount=1140, isValid=True); thus meshBody seems to be correctly formed. The mesh can also be exported and re-imported, another indicator of its data cohesiveness.

I am unsure which Forum I should post the problem to, D&V or API, so I will utilize both venues as a smart donkey would.

Hi Fellows,

THE MYSTERY SOLVED!

The Donkey has found the problem! He has Section Analysis switched on ... and it happened that XZ plane section was active!

Thank you, all ZOO Keepers, for your help and the Audience for the attendance.

Bray, bray, bray ....
