All drawing is done in model space, at a scale of 1:1. That is the golden rule of AutoCad.
1 AutoCad drawing unit can equal whatever, (be it metres, millimetres, inches, feet, miles, or light years).
But 1 AutoCad drawing unit can only = 1 whatever unit.
To set units up in the drawing, use the UNITS command, and fill out the dialogue boxes to suit requirements.

Once the drawing has been completed in model space, it is time to go to paper space and set up the drawing sheets for plotting.
Right mouse click on the model tab at the bottom left corner of the drawing screen, and select new layout.
287
Select the new layout tab and rename it to suit (e.g. plan).
288
Insert a standard drawing sheet, place lower left corner to cords 0,0. Then go to View > Viewports > 1 Viewport, and draw a viewport within the drawing area of the standard drawing sheet. Place the new viewport on a layer of its own and check it in Layer Properties Manager as No Plot.
289
The new viewport will show the extents of all drawing in model space.
Select the new viewport and type PROPERTIES on the command line. Go to the properties dialogue window and set the scale for the viewport (let’s use 1:500). Set the properties dialogue window up as shown, changing Linetype scale, standard scale, and custom scale to suit a plot scale of 1:500:

Next, double click inside the viewport, and pan the image of model space that is displayed, until that section of model space that is required is displayed within the viewport. Do not zoom in or out during this phase, or the viewport scale will be changed. Once the required section of model space is displayed within the viewport, select the viewport again and go back to properties, and lock the viewport (Display Locked).
Now the layout tab is ready to plot. Enter PLOT on the command line, but set the plot scale up at 1:1.
