rect1 = antenna.Rectangle("Center",[0 0],"Length",75e-3,"Width",37.5e-3);
rect2 = antenna.Rectangle("Center",[0 0],"Length",150e-3,"Width",75e-3);
p = pcbStack("BoardShape",rect2,"Layers",{rect1, rect2});
p.ViaLocations = [0 0 1 2];
show(p);
Error using surf2patch (line 47)
Z must be size 2x2 or greater.

Error in em.PCBStructures/makecylinder

Error in pcbStack/createGeometry (line 1081)
                    tempViaGeom{i}      = em.PCBStructures.makecylinder(dia/2,viaHeight(i),50,[vias(i,1:2) layer_heights(vias(i,4))]);

Error in em.MeshGeometry/protectedshow

Error in em.MeshGeometryAnalysis/show (line 31)
protectedshow(obj);

This is a script, if I run the script I get this error messege. I would like to add 2 vias (in this example I add only one, but I would like to know how I can add more) but I get this error, I don't understand why, there isn't one example on this in the documentation

Hello,

The visualization seems to fail because the ViaDiameter is empty.

rect1 = antenna.Rectangle("Center",[0 0],"Length",75e-3,"Width",37.5e-3);
rect2 = antenna.Rectangle("Center",[0 0],"Length",150e-3,"Width",75e-3);
p = pcbStack("BoardShape",rect2,"Layers",{rect1, rect2});
p.ViaLocations = [0 0 1 2];
p.ViaDiameter
ans =

     []
