measuring units and settings

[roccochiolo]

good evening gentlemen I would need your lighting, I have to draw a project of a house and I don't know how to set the measurements, I go up in the menu in size and seleziono unit, I put in meters and for the zeros after the comma I put two but if I create a line and while I select with the mouse there appears a number formed by so many digits if I should create a line of one meter and a half I should write 1.5

if you typed 1.5, followed by sending, the line will also be very small but is 1.5 long. measure it with a special command and see how long it is

Layout?? You mean layout maybe?
I think you have great difficulty working on model space, I can't imagine what you know about the layouts...questions: Are you following the tutorials that suggested you in previous posts?

zoom? What zoom?
zoom extension? that shows you all the space containing entities. If you have designed only one line that is 1.5 and 1.5e+100 you will always see a line going from one extreme to the other of the screen. if you have other entities scattered around the speech changes.
other zoom modes are susceptible to your decisions, if you see the very small line you're probably wrong to use the command.
If there are so many figures there is something that doesn't come back; you can abche make a line of 1,123456789, but if you set two digits after the decimals the cad makes you Information to two decimals while evaluating the value nine decimals.
Maybe the ones you read are the coordinates. . Perhaps
