c3d 2014 scale setup-what is units?

i am new to autocad and also c3d and i am trying to figure out how the scales and printng works.

c3d the last days drives me nuts and i do not understand what is going on.

first i am working in meters .meters is choosen under the drawing settings tab .

i am trying to test print at 1:1  a rectangle with 0.2 meters side that normaly will fit in a A4 sheet since the A4 is 0.21x0.297 METERS .

in the print dialogue i set the 1"mm" = 0.001 "units".

the result is an image multiplied by 1000  .

why that? arent the " units "   METERS? METERS is what i use in the drawing so why i get a biger image?


if i set 1"mm"= 1 "unit" and NOT 0.001 i get correct 1:1 print .

what i am missing?  c3d wants me to give 1mm=1meter????


please someone help.

another strange thing i noticed:

if i create new drawing from acadiso template i get layouts that are in mm .i mean that the "A4 210mmx297mm" is exactly that 210mmx297mm.

BUT in my drawing the "A4 210mmx297mm" is 0


how one layout is in mm and the other in meters?

how can i change that?

AotoCAD and hence Civil 3D uses the actual papersize units in layouts. So in a layout the units will be in mm's or inches. The scale that the modelspace entities will plot at is an attribute of the viewport and can be set in properties.
