Hi,
thank you for the details!
Open the file "T_ZTEMA_alt_AK.dwg" ... there you'll find a really long line ... delete that line and you'll have a clean plot.
I don't have a good explanation why it does that, but high coordinates are critical, especially when you have them in one line object.

HTH, - alfred -
