I am working Design Modeler and I am facing something I can't quite figure out, even with the manual. I was wondering if someone here may know really quickly.

Basically, I am trying to make a layer in the design moduler that has little islands in it.

Think of it like this: You have a 1" x 2" copper layer, but within the copper layer, you have mini 0.02" x 0.02" copper rectangles inside, each separated by an insulator.

So, the 2D layer, with little islands inside of it.

Any tips on how to make that happen?

I attached an image of what I made. Basically, I know how to create the layers and extrude them, but as you can see by the 2" x 0.02" strips in the middle, I don't know how to separate out the islands.

It would be much more easier if you create it in SolidWorks, any way, in DM you would have to define separate planes for each layer and define the location of plane by adding Transforms. Then create sketch on that plane.

You can draw lines on the sketch of the target 2D plane, then split the surface with the lines to create the islands.

BTW, this is something like the solar module, with two reinforce strips on the back.

Hmm.. I'm not sure if I follow this one. Do you know of an example I can base this on? (A link to an example that is, I know you mentioned solar module)

I think I may just do it in Solidworks, but a shame it can't be done that easily in DM. I consider my CAD to be pretty simple, its basically a mutli-layer rectangle with some islands on it.

Do you want to select the two slim islands to set boundary condition?

If I understand your question right, I do want the islands to be electrically separated and able to analyze effects in them, independent of the other islands.

There will also be more than two, closer to 20.

I am not sure your method to build model, but if it is right as the attachment shows, extrusion from sketch would help. And there may be no other more convenient way, as far as I know.

Or you need a separation layer under the small block to keep it unconnected from the base layer? If so, you can create a multibody part, assign different material to each body.And the mesh in the common surface would be consistent.
