pdegplot(m​odel1,'Fac​eLabels','​on')

Hello,

I have a question about the pdegplot command. The face labels are very hard to see, so it's hard to tell what faces correspond to what number. For some reason, my stl is broken up into 13 surfaces, with many small surfaces. Is there a way to tell matlab to merge the surfaces together and is there a trick to locating the number of the surface?

Thank You,

Vitaly

Sorry, at the moment there is no way to change the way that MATLAB infers surfaces from an STL file.

I suggest that you examine your surface using some transparency:

pdegplot(model,'FaceLabels','on','FaceAlpha',0.5)

Good luck,

Alan,

Thank you for your email.

Is 'FaceAlpha' a new feature? I am using Matlab 2016a and it does not recognize that feature and I don't think it's mentioned in the help document.

Thanks,

Vitaly

Yes, it is not supported in your version. Instead, use this workaround from the R2016a documentation:

h = pdegplot(model,'FaceLabels','on');
h(1).FaceAlpha = 0.5;
