Hello everyone,
your help would be highly appreciated.

Please refer to the visual embedded.

On the right I created the lines with the polyline tool, mirrored the lines and finally joined the lines.
I did the same for the shape on the right. But now the shape on the left is hollow when i extrude it and
the shape on the right is filled when i extrude it. I am confused?

How do i get a fill on the shape on the left?

Please advise. Thank you.
Sandeep.
