### Creating Feature Control Frame Dimensions

A Feature Control Frame (FCF) is a rectangular graphic that represents specified dimension information for one or more features. It usually appears on a blueprint or cad file to define tolerance specifications for specific dimension types. The ASME Y14.5 >– 1994 Geometric Dimensioning and Tolerancing describes appropriate use of Feature Control Frames (FCFs).

These FCF dimensions include:

- Form Dimensions: Straightness , Flatness , Circularity (Roundness) , Cylindricity

- Orientation Dimensions: Parallelism , Perpendicularity , Angularity

- Location Dimensions: Position , Concentricity , Coaxiality , Symmetry

- Profile Dimensions: Surface Profile , Line Profile

- Runout Dimensions: Circular Runout , Total Runout

To Create a Feature Control Frame Dimension:

1. Click the desired icon from the Dimensions (Plan) toolbar, or select the menu item from one of the Insert | Dimension (Plan) submenus. The FCF (Plan) dialog for that dimension appears.

2. Use the Feature Control Frame tab to select the features to dimension and to construct your FCF. See "FCF (Plan) Dialog Box - Feature Control Frame Tab" for information on the available options in this tab.

3. Click Create. PC-DMIS inserts a FCF command into your inspection plan.

Feature Control Frame Creation Conditions

In order for Planner to properly create a FCF dimension, it must meet the appropriate conditions for the type of dimension you want to create. Consult the following table as needed:

Dimension Type | Conditions to Meet
Form dimensions: | No datums. No material conditions. No projected zones.
Profile dimensions: | May or may not have datums. No material conditions. No projected zones.
Orientation dimensions: | Must have datums. May have material conditions. May have projected zones.
Runout dimensions: | Must have datums. No material conditions. No projected zones.
Position dimensions: | May have datums. May have material conditions. May have projected zones.
Other location dimensions (these include symmetry concentricity, coaxiality): | Must have datums. No material conditions. No projected zones.
