Dear All,

Thank you in advance

You want to enable the Polygon display type:

First of all thank you for your answer, but the function “Polygon” does not allow to have the 4 sides of the tetrahedra, but only two (as shown in the image below). Do you know how shall I draw the 4 faces of the tetrahedra.

Tetrahedra represent the the elementary components of glasses, it would be nice to include this option in future Avogadro software updates. Because for glasses structure, we have to go through another design logciel to complete the structures obtained with Avogadro software.

I’m not sure why that’s happening, but it’s clearly a bug.
