Display full length of path profile on Illustrator

NEV

I can no longer display the full length of a path profile (saved in GM 22,1as a Vector PDF) in Illustrator (2025). The profile is truncated at 30 km. I have been over all accessible settings in both GM and Illustrator and cannot find a reason. I have been drawing profiles for lengths greater than 30 km and opening successfully in earlier versions of both programmes for years.

What is causing this? I cannot find any clipping setting in GM Path Profile settings thaqt nmay be causing this.

I uninstalled and reinstalled Illustrator - but no difference. Reluctant to uninstall GM as I am using a dongle and it is some years since original installation.

Thanks,

Neville
