## Dimensioning Position In-Between

Position In-Between

The Insert | Dimension | Position In Between menu option computes the in-between position deviation and deviation angle from two specified Position dimensions. This dimension is useful when you have a set of position dimensions on a pattern of holes and you want to report the position deviation and deviation angle of one hole relative to another where each individual hole of the pattern has been dimensioned with a separate position callout.

Note: The ANSI or ISO standards do not include Position In-Between. This is special implementation unique to PC-DMIS.

To create this dimension:

1. Access the Position In Between menu option. The Position In-Between dialog box appears.

2. Select two dimensions from the Position Dimensions list. This list includes both legacy and Feature Control Frame (FCF) Position dimensions. If you select a composite FCF Position or a FCF Position with two single segments, PC-DMIS will only use the Primary Dimension to compute the Position In-Between dimension.

3. Type a label ID for the dimension by typing in the ID= box.

4. Type a tolerance value for the dimension in the Tolerance box.

5. Select the measurement units to use from the Units list.

6. Click Create.

The dimension will appear in the Edit window with this information:

dimension_name = POSITION IN BETWEEN dim_1 AND dim_2, UNITS=IN/MM

DEV is the deviation of the In-Between dimension. DEVANG is the deviation angle of the In-Between dimension.
