#### Dimension Options

This Graphical Analysis Options dialog box allows you to determine the information that gets displayed in the Analysis window.

Dimension Analysis Options

To access this option

1. Select Analysis from the menu. The Analysis dialog box will appear.

2. Select the dimension from the list box.

3. Click the View Window button. The Analysis window will appear.

4. Select Options | Dimension Options from the Analysis window. The Dimension Analysis Options dialog box opens. Most options are unavailable until you select any dimension in the Analysis dialog box. Relevant options become available for selection.

The following options are available on this dialog box:

Dialog Box Option | Description
Show Arrow Heads | The Show Arrow Heads check box turns the arrow heads on or off of the deviation lines.
Show Lines Between Meas. Hits | The Show Lines Between Measured Hits check box toggles on or off lines between the measured hits.
Show Lines Between Nominals | The Show Lines Between Nominals check box toggles lines drawn between the nominal values.
Show Tolerance Lines | The Show Tolerance Lines check box toggles the display of the acceptable tolerances for the dimension.
Show Max / Min Deviations | The Show Max/Min Deviations check box allows the maximum and minimum deviations to be indicated with a ' *+ ' or ' *- ' symbol.
Show Grid | The Show Grid check box lets you display a 3D grid-like backdrop for the graphical analysis. Enabling the grid may help you better visualize rotated items. It also enables the Grid Options button. Clicking Grid Options opens the Analysis Grid Options dialog box which you can use to define your grid.

Sample Graphical Analysis with the Grid enabled

Analysis Grid Options dialog box

The dialog box contains these options:

Automatically Size - This automatically sizes the grid based on the number of objects specified in the X, Y, and Z fields.

Specified Size - This enables the Maximum Boundary and Minimum Boundary boxes, letting you type specific sizes for the maximum and minimum boundaries.

Number of Elements - This defines the number of divisions that will be drawn on the analysis grid.

Maximum Boundary - This defines upper limits of the analysis grid coordinates.

Minimum Boundary - This defines the lower limits of the analysis grid coordinates.

Grid Options | The Grid Options button displays the Grid Options dialog box.
Multiplier | The Multiplier box allows you to enter a scaling factor that magnifies the deviation arrows and tolerance zone for the graphical analysis mode. If a value of 2.0 is entered, PC-DMIS will scale the arrows two times the calculated deviation for each feature hit.

This option is used for viewing purposes only, and is not reflected in the text only printout.

Show Diameters | The Show Diameters check box allows you to show the diameters of available Position dimensions.
Show Best Fit, Max Inscribed, and Min Circumscribed Diameters | This check box allows you to turn on or off the various diameters that may also be drawn with the Circularity dimension. These diameters are those that represent the average, maximum, and minimum deviations for a round feature.
Show Contour Plot | The Show Contour Plot option only works for patch scans and becomes available for Profile dimensions. The contour plot uses the patch scan points to create a mesh and then shades the mesh with the colors related to the profile deviations from each hit.

PC-DMIS also allows you to display the contour plot on the CAD model in the Graphics Display window itself. See "Displaying Profile Contour Plots" in the "Dimensioning Features" section.

Show Color Inter. Between Hits | The Show Color Interpolation Between Hits option allows you to insert colors between hits. This option is available for Profile dimensions.
Show Arrows | The Show Arrows option allows the arrows for deviation lines to be toggled on or off. This option is available for Profile dimensions.
Arrow Density | The Arrow Density slider lets you change the density of arrows for the points displayed in any dimension in the entire part program that uses Graphical Analysis. This differs from the Arrow Density functionality in the Advanced tab of the GD&T dialog box. The setting in the Advanced tab only affects that specific dimension. See "GD&T - Advanced Tab"in the "Using Feature Control Frames: Introduction" section.
