In NX by default for A4 size sheet, our edit sheet sizeis: A4- 210x297.
Please advise how to change it to A4- 297x210. I am working in NX12 migration and in NX11 A4- 297x210 is working.
This is a setting in the Customer Defaults. Most probably in your company Drafting Standards.
You should ask your CAD administrator to make this size available for you.
Above is a snippet.
