PCB layer mesh problem

How can I make the square influenced by the heat source?
You and find that the mesh densities of the square and the bottom layer are different. I know that if I make the square and the bottom layer as an union, it will work. But I am wondering if I can only make it as two layer, what should I do then?
I have a two layers PCB. but the top layer seems independent to the bottom.There is a thermal Isolation around the square. How can I change it?

Hi
I believe you cannot do it that way, a 2D model has a default 1m depth in Z but you cannot define Z layers in 2D, for that you need to go 3D, by first extruding your imported 2D geometry.
In 3D you do not need to use assembly mode, use geometry union mode, you will then split the surface of your 3D and on this surface cut you can define a thin layer of a conductor (use material BOUNDARY and not Domain type, you might need to add a second material for the boundary definitions, that I haven't had time to check in 4.3 yet ;)

Good luck
