How to write in model space in meters and in paper space in milimiters

[rodrigo_luizp]

I know this is a common question, i searched it all but i couldn't solve my problem.

I will start from zero!

So i create a acadiso.dwg file, and draw a 1 unit line in model space.
I go to paper space and open a Full Bleed A1 Paper on Page Setup.
I set my viewport to 1:1.

The result is:
Model space: 1 unit line.
Paper space: 1mm line.

The problem:
I want the 1 unit line to correspond to 1meter in 1:1 scale.
That way i would draw a 1 unit line on model space and set 1:100 scale so it would fit in the paper.

Basicaly right know i changed my scale manualy to 1000:1 so i get the effect i want.
I want to know if this is the only way and if this would cause problems with dimensions and etc.

Perfect thought!

Yes, the default scale-definition doesn't fit for meters->millimeter

You have to create your own scale, this "1:1" is just a name, it could also be named as "vanilla" or "Powerboat".

Use meaningful names, like 1:1meter

Edit the default list of acad here:

https://help.autodesk.com/view/ACD/2020/ENU/?guid=GUID-9C679D8F-DAE1-401E-AF6A-FF2D9C6963D8

And the scalelist in a dwg by command scalelistedit.

But if you edited the default list first, it is easy to use the RESET option from ScaleListEdit command in your templates *.dwt and any *.dwg you like.

One hint more: Please never edit default scale setting, delete the scales, rename and edit the scales, but never change just the definition).

And keep the original "1:1"

Thank you for the reply.

As of right now, when i try to edit the default scale list on the Options>User Preferences>Default Scale List.. Dialog, the changes i make there won't persist.
I googled it and it says i either should change the windows registry or keep a template file and copy paste it.

What do you think?

I think you are working on an obsolete productversion (2020), current is 2020.1 and this bug is fixed with this update.

Thank you very much for your help, my autocad was outdated as you said.

Now it works! 😁
