[Gmsh] Extrusion with dilation

[Mark Starnes]

Hi everyone,

Can you tell me if it's possible to perform a recombined, layer specified extrusion with a dilation, please?  I tried,

pcb5[] = Extrude {0, -pcbt, 0} {Surface{648}; Layers{1}; Recombine; Dilate{{0,0,0},1}; };

with hope but this throws an error.  I also tried dilating the surface after the extrusion but the meshing failed.  I ask, as it is clear rotation during extrusion is supported but can't see any mention of dilation.  I'm hoping I'm missing something!

Thanks in advance,

Mark.
