Drawing Units vs -DWGUNITS

[efioriniW9BJH]

Hi,

I have an issue on a specific drawing. I need to update the used units from inches to mm. I worked into the model doing the design in mm (1000 units=1000mm) but at the end I noticed that the drawing units were set  in inches so I switched in mm.

The problem is the following:

it seems that units remained as they were, this because if I copy paste a block to a blank drawing set in mm, the block was scaled wrongly.

In fact I noticed that while the Drawing Units is setting in mm (see following),  

the "-DWGUNITS" setting stay in inches, the first value it's 1 (see following).

How this is possible?

This is INSUNITS variable setting only, look up usage in HELP

This is you simply asking AutoCAD to use decimals: that can be mm, inches, feet, cm, meters, whatever, it means nothing else

If you want to change your drawing from INCHES to MM as you desire, DWGUNITS command is the place to do that. No where else unless you just start with a template set to mm so you can skip the conversion process.
