</a></p></li></ul></div></div><br clear="both" /></div></div></div></div></div></div></div></div><br clear="both" /><div><p>(Photoshop Extended only) Users ranging from architects
and interior decorators to forensic scientists and woodworkers often
need to know the size of objects in an image. In Vanishing Point,
the Measure tool lets you draw a measurement line over an object
in a perspective plane that you know the size of. The Measure tool has
an option for entering a length for the measurement. The measurement
line displays two text boxes: one for the length and one showing
the angle that the line was drawn relative to the perspective plane.
Once the measurement and its length have been set, all subsequent
measurements correctly scale to your initial measurement. </p>
<p>For a video on using Vanishing Point, see <a href="http://www.adobe.com/go/vid0019" target="_blank">www.adobe.com/go/vid0019</a>. </p>
<p>There’s an option for linking the line’s measurement length with
the grid spacing of the perspective plane. For example, a measurement
length of 5 causes the grid to display 5 spaces, when the link option
is selected. This might be useful for visualizing sizes in the image
or for counting objects in an image. When unlinked, the grid spacing
can be adjusted independent of the measurement. This option is useful
in such instances where you find that the grid spacing is too small
and visually confusing when linked to the measurement.</p>
<p>The measurements you create can be rendered so they appear in
the image after you close the Vanishing Point dialog box. You can
also export your measurements and geometric information to formats
that can be read by CAD applications.</p>
