Hello,

I have attached a simple cube. I would like to label the faces (F), vertices (V) and normals (N) of this STL file in the image. If possible I would like to limit the labels to just one of the faces. For example just the face with the face with the vertices 1, 2 and 3.

Can you show me how to do it?

Thank you :D

Edit: This is my code (more or less) and attached are the right files, the matlab figure and the stl file

Edit 2: I've corrected the code to show the edges.

FileName = 'Cube_3d_printing_sample.stl'
OpenFile= stlread(FileName);
[F, V, N] = stlread(FileName);
patch(OpenFile, ...          
       'FaceColor', [0.1 0.5 0.2], ...          
       'FaceLighting', 'gouraud', ...           
       'FaceAlpha', 1, ...           
       'EdgeColor', 'black', ...          
       'EdgeLighting', 'gouraud', ...          
       'EdgeAlpha', 1, ...          
       'AmbientStrength', 0.9);
