How to fill a polygon generated by importing a .dxf file to Altium?
No there isn't a way to import DXF with default copper fills, if the fills were not already there originally. This is out of the scope of a DXF import. You will need to select the contours of the area you want to fill and make a copy on another layer for back-up, then select the contour and &quot;create a polygon from selected primitives&quot; with the tools-&gt;convert commands etc. then you can fill in as you wish... You may need to then move your fills to the required layers.
