In model space, a model in Perspective view may display an actual distance.For example, if you create a linear dimension that starts in a SketchUp model entity and ends in a LayOut text box, the dimension text displays the distance in paper space. When a dimension crosses paper space and model space, the dimension text reflects paper space.For example, in the preceding figure, one linear dimension marks the length of 23 feet, 2 inches, even though the paper is only 11 inches wide. When you use the Linear Dimension tool to mark a length within a SketchUp model entity, the dimension text reflects the length in the SketchUp model. Everything inside a SketchUp model entity exists in model space. So the dimension text on a 6-inch line displays 6". When you use the Linear Dimension tool to mark the length of an element in paper space, the resulting dimension shows the actual size of the element on the page. Everything in your LayOut document that is not inside a SketchUp model entity exists in paper space. Unlike understanding, say, the four-dimensional space-time continuum, understanding space in LayOut is fairly easy. Understanding paper space, model space, and projected distances Managing and fixing dimension connections to SketchUp model viewports.
