6. Layoutting paper and printting output 6.1 Model space and Paper space There are two distinct working environments, or “spaces,” in which you can create objects in a drawing. Model Space A model that composed of geometric objects is created in a three-dimensional space is called model space. In model space, you draw your model at 1:1 scale, and you decide whether one unit represents one millimeter, one centimeter, and so on. Paper Space A final layout of specific views and annotations of this model is created in a two-dimensional space called paper space.

Paper space Paper space is a sheet layout environment where you can specify the size of your sheet, add a title block, display multiple views of your model, and create dimensions and notes for your drawing. Use paper space for composing your drawing sheet and defining views. In paper space, one unit represents the paper distance on a plotted sheet. The units will be in either millimeters or inches, depending on the plot setup for your plotter.

6.2 Creating layouts On a layout tab, each layout viewport is like a picture frame containing a “photograph” of the model. Each layout viewport contains a view that displays the model at the scale and orientation that you specify. You can also specify which layers are visible in each layout viewport. After you finish arranging the layout, you turn off the layer that contains the layout viewport objects. The views are still visible, and you can plot the layout without displaying the viewport boundaries.

6.3 printing output After you've created your drawing with AutoCAD you can print your designs on a sheet of paper or create an electronic plot that is accessible from the World Wide Web. A plotted drawing can contain a single view of your drawing or a more complex arrangement of views. Depending on your needs, you can plot one or more viewports or set options that determine what is plotted and how the image fits on the paper.
