contour
Contour cut out  Your document will be cut on the contour lines. Please note, this is an "expert" option: it is fairly complex to provide this properly in your file. Deliver your document with a separate layer for the contour lines. Look here for instructions.
The contour lines are visible as a blue line in the preview. If the contour lines have not been delivered correctly, a message will appear. Don't see an error? Then you did well!
Complex figures (many sharp corners/very small forms) are difficult to produce and therefore this is not possible.
