A macro pointing at a contour that is not there

UnsupportedRefused. No file is produced.

What the converter says

the macro routes contour 7, which the file does not hold

Code: mpr_contour_missing

What triggers it

The routing macro names a contour by number and the file holds no contour with that number.

<105 \Konturfraesen\
EA="7:1"

Example that triggers it

How to fix it

Check the macro's start and end references against the contours in the file. A contour deleted after the macro was written is the usual cause.
