To scale each displayed view accurately for output, set the scale of each layout viewport.

When you work in a layout, the scale factor of a view in a layout viewport represents a ratio between the actual size of the model displayed in the viewport and the size of the layout. The ratio is determined by dividing the paper space units by the model space units. For example, for a quarter-scale drawing, the ratio would be a scale factor of one paper space unit to four model space units, or 1:4.

You can change the view scale of the viewport by using

• The Properties palette(Custom scale)
• The XP option of the ZOOM command when model space is accessed from within a layout viewport(Zoom-Scale)
