How do I change units in an existing drawing

Post by Rochus » Thu Jan 22, 2015 5:49 am

Hello everyone,

I have QCAD version 3.7.6.0 with Windows 7 :

I'm using an existing drawing about a factory but the previous owner did it in inch but I need it to be in millimeter.

My drawing unit in the "Drawing Preferences" and "Application Preferences" are in Millimeter but the number showing when I use the "Dimensions Tools" (then "Aligned DA" button) are still in inch.

What can I do to set it in millimeter ?

Thank you.

Hello Rochus,

After you changed the Unit in "Drawing Preferences" from inch to mm you have also to scale the whole drawing.

Ctrl + A
"Scale" Tool,
Reference point: Absolute 0 (?)
Scale Dialog: Delete Original, Scale Faktor = 25.4
Now everything should be in mm.

Maybe you have also to adjust the "Drawing Preferences / Dimension" Settings.

Will that work for you?

Is there a way to prevent having to manually scale the drawing, after you switching units?

Yes! This topic is already 5 years old and QCAD developer implemented meanwhile a function which is called "Convert Drawing".

You will find it below Menu / Edit. Change the unit and the scaling will be done by QCAD ... :wink:
