I would like to import an .stl file. I proceeded like this:
fv = stlread('EXAMPLE.stl');
patch(fv,'FaceColor', [0.8 0.8 1.0], ...
'EdgeColor', 'none', ...
'FaceLighting', 'gouraud', ...
'AmbientStrength', 0.15);
grid off
hold on
axis equal
But I wanted to get a figure with the outline. What should I change?

Look into the following code which imports the sample .stl file into MATLAB and adds the geometry to the PDE model.
In the “pdegplot()” function change the parameter “FaceAlpha” to "0" so that only edges are shown from the geometry present in the .stl file
model = createpde;
importGeometry(model,'cube.stl');
pdegplot(model,'FaceLabel','on', 'FaceAlpha',0)
Results of the about code with the sample cube geometry is as shown below.
With “FaceAlpha = 1”
Results of the about code with the sample cube geometry is as shown below.
With “FaceAlpha = 0”
Refer this "Link" for further information on importing the .stl file and changing the parameters.

Thanks, but I had already seen that link. Using the createpde command I can't get what I want because the stl object is characterized by a mesh.

Why is the answer always to use the PDE toolbox tools for general STL import?
It doesn't answer this question. For what appears to be the meaning of "the outline", the answer would simply be to use an EdgeColor other than 'none'. Instead, you sent OP on a wild goose chase to try and get the facet edges of the original model to show in pdegplot(). You're leading the user away from the thing they asked for.
