When you select the Graphical check box (or the On option for Location and Position dimensions) for a dimensioned feature (Insert | Dimension), the software shows a graphical output of the dimension in the Graphic Display window for review.
When you select the check box, PC-DMIS graphically displays the deviation of each individual hit for the dimensions used on the part in the Graphic Display window.
The measurement routine displays errors as individual arrows for each hit. These arrows, with their colors and directions, indicate the relative size of the error, as well as its direction.
For the Position, Concentricity, and Coaxiality dimensions, PC-DMIS shows the position of a feature with one or more arrows. For Symmetry dimensions of width features, PC-DMIS shows the points that make up the center plane.
Command line in the Edit

Consider this example which uses the dimension information displayed in the textual analysis example in "Textual":
Example of a Circularity Dimension using Graphical Analysis with a multiplier of ten (on the left) and one (on the right)
The Circularity example above contains various colored lines, arrows, and circles. The following describes the colored elements in the example and what they mean:
Black Circle = Shows the nominal circle.
Red Circle = Shows the measured, out-of-tolerance circle.
Blue Circles = Show the tolerance bands.
Colored Lines = Show the lines between hits.
Colored Arrows = Show the hits themselves (the tip of the arrow), the relative size of the deviation for each hit (by the colored arrow), and in which direction deviation occurs (the direction the arrow points).
The colors used in this example are the default dimension colors. You can easily change these colors if desired. The colors used will also correspond to the colors used on the bar graph on Dimension Info and Point Info boxes. See "Editing Dimension Colors" in the "Editing the CAD Display" chapter.
