Depending on the FCF dimension you are creating the three analysis lists will contain some of the following items:

- ON - PC-DMIS will enable that type of analysis.

- OFF - PC-DMIS will disable that type of analysis.

- POSITION - PC-DMIS will enable that type of analysis but will only analyze the dimension's location.

- FORM - PC-DMIS will enable that type of analysis but will analyze the dimension's form.

- BOTH - PC-DMIS will enable that type of analysis but will analyze both the location and form of the dimension.

- If you create a Profile form and location FCF dimension (requires datums), the available options are OFF, POSITION, FORM, BOTH since you can request analyses for position (location) and/or form.

- If you create a Profile form only FCF dimension (no datums), the options are OFF, FORM since you can request an analysis only for form.

- If you create a True Position FCF dimension, the options are OFF, POSITION, FORM, BOTH since you can request analyses for position and/or form. The form axis can be selected from the list of axes within in the True Position area.

- For all other dimensions, the options are ON, OFF.

When you select to follow this standard, PC-DMIS applies the following changes:

- It calculates the profile deviation as two times the max deviation.

- It clears the Deviation Perpto Centerline check box by default. You can later select the check box if desired.

- It selects the Fit to Datums check box by default. If you then clear this check box, the drop-down list will change to Non-Standard.

- It calculates Axial/Radial runout according to this standard.

- Coaxiality uses the concentricity symbol, a diametrical symbol precedes its tolerance, and it allows MMC/LMC on considered feature and datums.

- Symmetry allows modifiers for MMC / LMC on considered feature and datums.

- Material condition symbols are (for MMC), (for LMC), and a blank (for RFS).

When you select to follow this standard, PC-DMIS applies the following changes:

- It calculates the profile deviation as (max deviation – min deviation).

- It selects the Deviation Perpto Centerline check box by default. You can later clear the check box if desired.

- It selects the Fit to Datums check box by default. If you then clear this check box, the drop-down list will change to Non-Standard.

- It calculates Axial/Radial runout according to this standard.

- Coaxiality tolerance is preceded by a diametrical symbol. It allows for MMC/LMC on considered feature and datums.

- Symmetry is only at RFS for both considered feature and datums.

- Material condition symbols are (for MMC), (for LMC), and a blank or (for RFS).

Selecting this doesn't follow a particular standard, so nothing is really changed. However, PC-DMIS will change the drop-down list to Custom and will gray out the other items, if you do any of the following:

- Attempt to dimension the parallelism of a plane with a projection length/width or diameter

- Clear the Fit to Datums check box

- Select the R symbol in the size tolerance for a true position dimension.

Axes | Description
X | The X axis
Y | The Y axis

PA | The Polar Angle value
PR | The Polar Radius value
D1 | Diameter /Width of the first datum
D2 | Diameter/Width of the second datum
D3 | Diameter/Width of the third datum

LF | Length of the feature if the feature is a slot
WF | Width of the feature if the feature is a slot
LD | Length of the datum if the datum is a slot
WD | Width of the datum if the datum is a slot

### GD&T Dialog Box - Advanced tab

GD&T dialog box - Advanced tab

The Advanced tab provides you with the ability to set output and analysis options for your Feature Control Frame (FCF) dimensions. For documentation on this tab, see the list of dialog box items discussed below. Also, note that much of this functionality already exists in the legacy dimensions and is discussed in detail in the "Dimensioning Features" section.

Output area - The Report and Statistics list allows the feature control frame output to be printed to either the inspection report or to statistical files used by statistics software (such as DataPage), to both of these, or to none at all.

- STATS – sends output to statistical files

- REPORT– sends output to inspection report

- BOTH – sends output to both inspection report and statistical files

- NONE – doesn’t send output anywhere

When PC-DMIS executes a FCF command, the output will go to the inspection report, the stats file, both of these, or none of them, depending on what you selected.

Note: If either the Stats option or the Both option is selected, a preceding STATS/ON command must exist inside the Edit window for the FCF to be sent to the stats file.

The Units list allows you to determine the units of measurement your FCF should use. You can choose between these options:

- IN = Inches

- MM = Millimeters

PC-DMIS uses the selected unit of measurement for dimensioning as long as the dialog box remains open. By default, PC-DMIS uses the same unit of measurement used by the current part program.

Tip: When creating more than one FCF in your part program, you don't need to continually define your settings in the Output area. Instead, PC-DMIS will automatically check your cursor position in the Edit window. If it finds a FCF at the current position, it uses those settings. If it doesn't, it searches up in the Edit window and uses the settings from the immediately preceding FCF.

Analysis area - This area sets the dimensional output analysis format for the FCF. It contains three drop down lists for different types of analyses:

1) Report textual analysis - This type of analysis prints out in a text format the following items in the standard inspection report and the Report window for each individual hit used in the FCF:

- Measured X, Y, and Z values

- Measured I, J, and K values

- Deviation of each individual hit

- “MAX” or “MIN” marker at the end of the line whenever the hit produces either a maximum or minimum deviation.

2) Report graphical analysis - This type of analysis displays in a graphical format that uses colored arrows, the deviation of each individual hit for the FCF used on the part in the report. These arrows, with their colors and directions, indicate the relative size of the error, as well as its direction.

3) CAD graphical analysis - This type of analysis works the same as the Report graphical analysis except that it displays the graphical analysis inside the Graphics Display window.

Description of ON, OFF, POSITION, FORM, and BOTH Items

Available List Items Based on Dimension Type

Arrow Multiplier - The Multiplier box let you set a scaling factor that magnifies the deviation arrows and tolerance zone for the CAD Graphical Analysis mode. If you type a 2.0 value, PC-DMIS will scale the arrows two times the calculated deviation for each feature hit. The Multiplier box is used for viewing purposes only, and is not reflected in the text printout.

GD&T Standard area - This area provides you with a drop-down list that lets you choose what type of GD&T standard your FCF dimension will follow. Available options include ISO 1101, ASME 14.5, and Custom. If you select ISO 1101 or ASME Y14.5 PC-DMIS changes different GD&T settings and calculations so that it follows the selected standard. PC-DMIS will automatically select Custom from this list if you do something that extends or customizes the previous selected standard.

ISO 1101

ASME Y14.5

Custom

Note: In version 4.4 and higher, you should use the GD&T Standard area to set the standard used for FCF dimensions. For legacy dimensions, you should continue to use the UseISOCalculations registry entry.

Dimension Info area - This area lets you create a Dimension Info text box for the FCF. When you select the Create Dimension Info when this dialog closes check box, PC-DMIS enables the Edit button. You can click the Edit button to open up a dialog box that lets you set default options for the Dimension Info command (DIMINFO). See “Edit Default Dimension Info” for more information.

When you create your FCF, the dialog box closes and PC-DMIS creates a DIMINFO command in the Edit window after the FCF. This DIMINFO command displays all dimension information in the Graphics Display window next to the feature selected from the Feature list in the Feature Control Frame tab. It also displays the same available dimension axes used in the Edit window for that particular FCF.

For more in-depth information on DIMINFO boxes and on rules governing their creation, see “Inserting Dimension Info Boxes” in the “Inserting Report Commands” section.

True Position area - If you are creating a FCF of True Position, Perpendicularity, Parallelism, Angularity, or Profile and the FCF uses datums of size at MMC or LMC, and the FCF contains axis information that requires you to define a size tolerance then this area becomes available for selection. For other FCF types or conditions it remains grayed out, with Straightness of a cylinder feature being one exception (see "Straightness Feature Control Frame Information"). This area contains these items:

Alignment - Sometimes when you view dimension information relative to the current alignment, the calculations of the datums can sometimes be hard to decipher. This list lets you determine how this information should get displayed: relative to a particular alignment or relative to the datum reference frame.

Fit to Datums - This check box determines whether or not the FCF uses a best fit calculation to find the optimal position of the datum reference frame that minimizes the error.

Deviation Perpto Centerline - This check box determines whether PC-DMIS calculates the deviation perpendicular to the feature's theoretical centerline or perpendicular to the direct X, Y, and Z values. See the "Deviation Perpendicular to Centerline" topic in the "Dimensioning Features" section for more information on this functionality.

Nominals and Axes - This portion lets you customize the output by controlling which axes PC-DMIS should display in the report and allowing you to manually type the nominal values.

Feature List - The list to the left of the Nominals and Axes columns displays all the features used in the FCF. When you access the Advanced tab, PC-DMIS automatically selects the top-most feature (or feature set) from this list and displays it's information in the columns to the right. If more than one feature is present, you can select just that feature, to display and edit its specific information.

Report Axis - This column contains check boxes for each axis. A selected check box sends that axis to the report.

Axis - This column lists the available axes
for the selected feature. Those axes that relate to size allow you to apply a plus or minus tolerance.

Nominal - This column contains nominal values. You can overwrite them by clicking on them and typing different values.

+Tol / -Tol - The plus and minus tolerance columns provide fields into which you can type tolerances for the various axes used in your FCF. PC-DMIS only applies these tolerance values to axes that relate to size, since the axes that control position use the main tolerance in the FCF.

Update Feature Nominal - This column lets you specify whether or not any changes you made to the nominal values should get applied not only to the FCF but to the feature as well.

Profile area - This area lets you define the Best Fit Algorithm to be used for Profile dimensions. This is only enabled when you are creating a Profile Line or Surface Dimension and you have select the Form Only option on the "Feature Control Frame tab"

- No Fit - No alignment is created.

- Least Squares - This fit finds a position where the deviations are minimized. In this way, the Form Only option can ignore the location of the feature while checking that the curve is close to the nominal shape.

- Vector - This fit snaps errors in the input features onto the theoretical vectors before minimizing the average squared error.

Iterate and RePierce CAD area - This area only appears for Profile dimensions in the case of form only. In versions before 2009 MR1, when a Profile dimension was created, PC-DMIS internally used an alignment to try to match the theoretical and measured hits. The alignment would automatically iterate and re-pierce if the machine was a portable machine and PC-DMIS was in surface mode. This area now lets you control whether or not this iterate and re-pierce operation occurs and what Tolerance and Max Iterations values to use.

For information on this area, see the information on the same Iterate and RePierce CAD area in the "Description of the Best Fit Alignment Dialog Box" topic located under the "Creating and Using Alignments" section.
