In this example, we have a drawing for different views of a hammer. The unit for length used in the drawing is millimeters. The general dimensions of the hammer are shown in white in the following figure:

The first step is to draw an enclosing rectangle, illustrated in yellow in the preceding figure (you can delete it later), and measure it to get the dimensions of the area that will be printed. In the preceding figure, the dimensions are 433 mm x 247.5 mm. An A4-sized paper in landscape orientation has dimensions of 297 mm x 210 mm, so by using a scale of 1:2, the drawing will fit on an A4 paper's printable area.

The following is a step-by-step tutorial for setting up the layout tab and creating and setting the viewport, starting with the steps for setting up the layout tab:

1. Click on the Layout1 tab to activate it, then right-click on the tab name and choose Page Setup Manager.
2. The Page Setup Manager window will show up. Make sure Layout1 is selected, then click on Modify to open the Page Setup window.
3. In the Page Setup window, set the printer to any of the AutoCAD PDF options (normally, you would choose the printer you will use but for now, we will just choose AutoCAD PDF). Choose ISO A4 (297 x 210 MM) for the paper size, make sure that mm is chosen for the units, and set the scaling factor to 1:1, as shown:

After setting up the layout tab, you can draw a border frame inside the printable area and add a title block, then  create and set the viewport, as in the following steps:

1. Start the Polygonal viewport command and draw a viewport, avoiding the area occupied by the title block, as in the the following figure.
2. Select the viewport, click on the small arrow to open the preset standard scale factor list, and select the 1:2 scale.

3. Delete the yellow dashed line and dimensions from the model:

That's it for the first example. Let's now look at the next example, which is a drawing for a small apartment.
