looks like you have 10mm shown as 0.3937"
Have a look at main menu:
Drawing Preferences -> Dimensions -> Length Factor

Like the subject title says when I enter a line length of 10 and make the line and then use the dimension function it has a line length of 0.3937 in LibreCad. Is there something that I need to change in LibreCad to correct this. Or am I doing something wrong.
Thanks,
Bob
