Viewport scale list 1:500 doesn’t work but z 1/500xp does

[Khernmega85]

I’m in 2025 Arch and drawing in meters, setting up a page to print. Page setup units are 1:1 (1mm =.001 units).

When selecting 1:500 in the scale list the viewport zooms in super close (incorrectly), but using the z 1/500xp command calibrates the viewport correctly https://xender.vip/ .

Am I missing something for why the viewport scale list isn’t scaling properly?

Hi,

Can you explain it please?

Enter Scalelistedit command then select 1:500 to edit and see if the entry shows a different value compared to 1/500

Are you 100% sure your DWG file is mm based? Plot scales are based on mm, if your DWG is set to anything else (meters for example, or worse, inches) you have some calculating to do.
