I have used the function (plotIGES) to plot a 3D IGES surface(as shown in the picture and attached).And I want to extract the edges of the whole surface and the hole(s) in it?
According to plotIGES function the surface can be plotted as triangular patches or triangular mesh as shown
FacePlot=plotIGES(ParameterData,1,1,1000,1,10,1,'r');%you can change the second input to 2 to get triangular mesh
xlabel('X')
ylabel('Y')
zlabel('Z')
Help would be appreciated.
Thank you so much.

clear all
load fv.mat ;
%
tri = fv.faces ;
coor = fv.vertices ;
[e,te,e2t,bnd] = connectivity(coor(:,1:2),tri) ;
triplot(tri,coor(:,1),coor(:,2))
hold on
plot(coor(bnd,1),coor(bnd,2),'*r')

This was good for .stl file format. But thank you so much for the great effort.
