Delete internal faces from 3D plot
显示 更早的评论
Hello everyone,
I'm try to export the finite element into the STL file by using "stlwrite" function
The corrdinates and corresponding face are attached in "Coords" and "faces" files.
Now, I'm trying to plot 3D geometry by
fv.faces = Faces;
fv.vertices = Coords;
patch(fv,'FaceColor', [0.8 0.8 1.0], ...
'EdgeColor', 'b', ...
'FaceLighting', 'gouraud', ...
'AmbientStrength', 0.15);
camlight('headlight');
material('dull');
The result of plot are depicted as
However, when i zoomed the 3D geometry, the result appeared internal faces as
I want to eliminate all of the internal faces inside this geometry to get the continuous homogeneous solid.
Any comments or suggestion are appreciated.
Thanks in advances.

You could manually remove the faces as such:
Coords = [ 0 2 0
0 2 1
0 3 0
0 3 1
0 4 0
0 4 1
1 2 0

1 3 0

Faces = [ 1 3 4
