Copper plane with complex shapes

albertopv

Hello all,

I need to create a copper plane in a relatively complex shape for my actual design. I have tried without any success importing a .dxf File with the shape description, as the tool only seems to work properly with outlines and not with surfaces.

The shape is something similar to this:

Do you have any idea on how I could achieve this?

Thank you very much in advance! Slight smile

    I'm sure if you export a simple dxf you can import this shape so can you post the dxf file? The alternative is to use the Add commands with the Manufacture - Drafting options to construct this.

    Hello Steve,

    thank you very much for your fast reply. This is the dxf file which I am using without success.

    OK so as I said this dxf contains complex items (polylines). I opened this in draftsight and resaved as a R12 ascii dxf, you can then import that. shape1.zip

    Very nice! Unfortunately I am working with the version 16.6 and I cannot open that design but I will convert my files to the format you mentioned Slight smile

    I managed to convert and import the dxf file but I still have an outline, which I would like to fill with copper. Do you have any hint on how I could do that?

    You will NEED to have access to a mech tool (such as AutoCAD)

    The method goes something like this:

    1. In the Mech Tool: Open the .DXF

    2. Select one of the elements.

    3. Edit Properties -> Convert to PolyLine.

    4. Then select that element and also all the other.

    5. RightClick to "Join"

    6. If the elements are connected, they will now join and form one

    closed polyline. This can now be imported into a shape.

    In Cadence PCB Editor:

    Use "incremental import"

    Open the translation menu and select the .DXF-layer

    and map that one to a suitable etch-layer of your choise.

    If the lines in the geometry you are trying to import is on

    different .DXF-layers then you will have to heal the geometry

    and make sure that all line elements are connected to one another.
