double sided poligons

 Is possible to produce double sided poligons in Nvil? Also how to be sure that there is no any double sided poligons?

В поли моделинге это невозможно, нормали не позволят так сделать, влюбом случии надо немного утолщить.

Nvil does not allow the creation of Non-manifold geometry, the modeling commands will just fail to compute the result.


So you cannot duplicate a polygon and then weld vertices as an example.  They would have to remain as seperate geometry.

Look for the flip faces command if you want to flip normals.
