    Unhappy Need Help with scales for working in Meters

    Registered forum members do not see this ad.

    I'm new to Autocad (12) and have a question that is really puzzling me, I do the following:

    a.) open a fresh acadiso.dwt template file
    b.) define a standard paper setup for layout1, paper is set to 8½x11 landscape
    c.) run UNITS from the command line, for type: decimal, for insertion scale: meters
    d.) I draw a line .2 units long in model space
    e.) I set the viewport scale to 1:1 in layout1 and observe my line

    What I see is a line drawn .2mm long instead of .2m, why is that? Shouldn't the line be .2m long spanning almost my entire sheet since I set my drawing units to meters and want to see a real-size view of 1:1?

    thanks for any help!

    Welcome to CADTutor.

    The default data base units for the acadiso template are milliimeters.
    If you want to change to meters, use the -dwgunits command (include the hyphen) instead.
    Read and follow the commandline prompts carefully, and you will be walked through
    setting it up.

    Your working in metric one advantage is 0.2 is 0.2 wether it be mm or m you need to make a choice if you want mm then it should be 200 the main change will be when dimensioning you can draw in m 0.2 but dimension as 200mm the dim style would have the 1000 scaling set in it. What I am saying is you can mix and match draw in mm but have some dims in metre then scaling is 0.001. The quick answer on scale will be 1:1 or 1:1000

    We work with units set to unitless meters or mm just play with scale.

    Also if metric use A4 paper size.

    I drew a line 200 long then inside the mview Z E then Z 1XP line fits snug as A4 is 210x297 scale 1:1

    thanks for the warm welcome

    I ran -DWGUNITS and switched out of mm and into m but it still doesn't work. My model space units still get drawn as mm inside a 1:1 paperspace viewport. It seems no matter what I try paperspace can only see millimeters as the drawing units

    Drawing units:
    1. Inches
    2. Feet
    3. Millimeters
    4. Centimeters
    5. Decimeters
    6. Meters
    Unit for length <3>: 6

    Drawing unit display formats:
    1. Scientific
    2. Decimal
    Linear display format <2>: 2

    Linear display precision <4>: 4

    Scale objects from other drawings upon insert? [Yes/No] <Yes>: y

    Match INSUNITS to drawing units? [Yes/No] <Yes>: y


    ** WARNING: you have changed the unit for this drawing database. **
    ** All new objects will be drawn according to the new unit, but **
    ** existing objects will not change size unless you specifically **
    ** ask to have automatic scaling occur. **

    Scale objects in current drawing to reflect change in units? [Yes/No] <Yes>: y>:Yes

    Thanks for the reply. I haven't looked at dimensioning yet, I'm just wondering why it is paperspace views everything inside model space as mms. I even tried switching out of mm and into m using -DWGUNITS.... paperspace continues to see modelspace drawing units as mm

    After everything you showed, there was another question at your commandline,
    include objects in Paperspace? how did you respond to that?

    tried both y and n, same result

    do you have settings that work?

    thx. again

    I would be happy to look at the drawing for you, I am too busy right now to try and talk you through it.
    Can you post the drawing, so that somebody can check it out for you?

    Actually it's just the standard acadiso.dwt template file with a .2 unit long line drawn in modelspace. I'm just trying to understand why a 1:1 viewport in paperspace won't recognize meters as the drawing units.

    It will, see the screenshot.
    Set your -dwgunits value before you draw the line to 6 for meters, and give it another try.
