Hi, i need to figure some stl files and it's giving me an error
Error using patch
Value must be of numeric type and greater than 1.
Error in rysujPATCH (line 63)
czlon11=patch('Faces',C11.Faces,'Vertices',C11.Vertices,'FaceColor',C11.FaceColor);
matrixes are included
this is the code
%%
% Rysuj czlony
P2=C2.Vertices';
Unable to resolve the name 'C2.Vertices'.
P3=C3.Vertices';
% ustawianie czlonow
P2=F12(0)*[P2; ones(1, size(P2, 2))];
%
C2R=C2;
%
C2R.Vertices=P2(1:3,1:size(P2, 2))';
%
P3=F12(0)*F23(0)*[P3;ones(1,size(P3, 2))];
%
C3R=C3;
C3R.Vertices=P3(1:3,1:size(P3, 2))';
%% rysowanie
figure(1);
axis([-100,400,-100,400,-100,700]);
grid on;
hold on;
%
czlon11=patch('Faces',C11.Faces,'Vertices',C11.Vertices,'FaceColor',C11.FaceColor);
%%
%czlon12=patch(C12);
czlon12=patch('Faces',C12.Faces,'Vertices',C12.Vertices,'FaceColor',C12.FaceColor);
%
%czlon2=patch(C2R);
czlon2=patch('Faces',C2R.Faces,'Vertices',C2R.Vertices,'FaceColor',C2.FaceColor);
%
%czlon3=patch(C3R);
czlon3=patch('Faces',C3R.Faces,'Vertices',C3R.Vertices,'FaceColor',C3.FaceColor);
clear P2 P3 C2R C3R
I've already add +1 to whole faces matrix and still no luck.
Please help
EDIT: I've exported the stl files from SOLIDWORKS 2024

I was not able to get these to work with patch (I still do not understand what that problem is), however with a minor modification, I was able to get them to work with the trisurf function —
load('matrixes.mat')

Experimenting with the surface lighting —
figure
trisurf(C11.Vertices-1, C11.Faces(:,1), C11.Faces(:,2), C11.Faces(:,3), 'FaceColor',C11.FaceColor, 'EdgeColor','none')
lightangle(-45, 25)
lighting('flat')
title('C11')
figure
trisurf(C12.Vertices-1, C12.Faces(:,1), C12.Faces(:,2), C12.Faces(:,3), 'FaceColor',C12.FaceColor, 'EdgeColor','none')
lightangle(-45, 25)
lighting('flat')
title('C12')
figure
trisurf(C2.Vertices-1, C2.Faces(:,1), C2.Faces(:,2), C2.Faces(:,3), 'FaceColor',C2.FaceColor, 'EdgeColor','none')
lightangle(45, 65)
lighting('flat')
title('C2')
figure
trisurf(C3.Vertices-1, C3.Faces(:,1), C3.Faces(:,2), C3.Faces(:,3), 'FaceColor',C3.FaceColor, 'EdgeColor','none')
lightangle(45, 65)
lighting('flat')
title('C3')

That worked thanks. I'm quite new in matlab. I've other issue but that needs next ticket

Experiment with the lightangle arguments to get the result you want —
load('matrixes.mat');
figure
trisurf(C11.Vertices-1, C11.Faces(:,1), C11.Faces(:,2), C11.Faces(:,3), 'FaceColor',C11.FaceColor, 'EdgeColor','none')
hold on
trisurf(C12.Vertices-1, C12.Faces(:,1), C12.Faces(:,2), C12.Faces(:,3), 'FaceColor',C12.FaceColor, 'EdgeColor','none')
trisurf(C2.Vertices-1, C2.Faces(:,1), C2.Faces(:,2), C2.Faces(:,3), 'FaceColor',C2.FaceColor, 'EdgeColor','none')
trisurf(C3.Vertices-1, C3.Faces(:,1), C3.Faces(:,2), C3.Faces(:,3), 'FaceColor',C3.FaceColor, 'EdgeColor','none')
lightangle(45, 65)
lighting('flat')
% material('metal')
hold off
axis('equal')
view(-45, 20)
Ax = gca;
Ax.Visible = 0;
sgtitle('Assembled Segments')
