I have a shape for my PCB as follows in the picture below which includes four holes.
However, when I select the whole shape on Altium Designer and then select PCB from selected shape, it will only leave me the PCB as small round as you can see in this picture:
I wonder how can I make the PCB shape keeping the outer shape as the boarders of the PCB where the 4 circles are holes/vias.
The above answer does not account for the holes, which was your question. I've shown below the correct answer on how to do this, creating a quick example PCB to illustrate.
Select all shapes from your DFX file. Design -> Board Shape -> Define from Selected Objects. As you note, even selecting "cutouts" here doesn't do what you'd like. I think it's a bug.
And the resulting board shape.
Now select the holes. For some reason I had to do this step for each one, it wouldn't let me batch select. Tools -> Convert -> Create Board Cutout from Selected Primitives.
The resulting PCB including holes:
If this answer solved your problem, please consider selecting it as the correct one. Thanks, and hope this helps.
First check if you have closed lines. Go to PCB inspector and check line connections. Select each of the line with Shift pressed (multi select), go to Design-> Board Shape ->Define from selected objects
Automatic algorithm is not good for that.
