Change Flat's plan scale

Vanni
This post was updated on .
I realized the planimetry of my flat using as a main unit the "mm" (millimeter) and now I'd like to transform the drowing using as a main unit the "m" (meter)
May I transform the drowing just with some commands changing the scale or do I have to remake the drawing?
I'm a new user and, even if I tried many times to transform the drawing from "mm" main unit to a "m" main unit, I didn't succeed
Thanks in advance for any suggestions

Welcome Vanni!

You can use Modify -> Scale to scale down the whole drawing by factor 1000 and then set the main unit in Current Drawing Preferences to Meter.
Changing the main unit only does not change the drawing, it just defines the measure of one drawing unit and 1mm becomes 1m. So scaling is needed too.
See https://docs.librecad.org/en/2.2.0_a/ref/tools.html#modify

But you can also change Length factor to 0.001 in Dimensions settings in Current Drawing Preferences. This keeps the drawing as mm, but the dimensions will change to Meter.
See https://docs.librecad.org/en/2.2.0_a/ref/draw-prefs.html#dimensions
and https://docs.librecad.org/en/2.2.0_a/guides/annotate.html#dimensioning-appearance

Both are common technics and which one is used depends on personal preference and probably requirements when collaborating.

More details for method 2, scaling dimensions:

General Scale in Dimension settings is to scale arrows, text and extension lines. It is meant to scale up/down the dimension decoration on large/small drawings.
In this case General Scale should be like 1000 or possibly more or less, depending on overall size of the drawing.
Basically General scale is to modify the dimension style to make it readable on a scaled printout and it must not match the unit scale factor.

Length factor is what modifies the measurement value and must be 0.001 when a mm drawing is annotated in m.
See my references above.
