Probing a Part Datum Point The part datum can be created directly by probing a point. To probe a part datum point: 1 Select the desired probe from the probe menu. Measure toolbar > Probe menu > Desired probe 2 Press the Datum button. Measure toolbar > Datum button 3 Probe the desired point and press the Enter button or the probe prompt window. Measure toolbar > Enter button 4 Press the Done button to complete the measurement and enter the part datum point into the Feature List. Measure toolbar > Done button Constructing a Part Datum Point from one or more Parent Features The part datum can be constructed from one or more parent features when simply probing the desired point is not convenient or possible. Supported point constructions are specified in Section 4: Measuring, Constructing and Creating Features. To construct a datum point from a single feature: 1 Press the Datum button. Measure toolbar > Datum button 2 Select (highlight) the desired parent feature or features in the Feature List or Part View. 3 Press the Done button to complete the construction and enter the part datum point into the Feature List. Measure toolbar > Done button Creating a Datum by Manually Zeroing the X and Y Coefficients of a Feature Any of the features contained in the Feature List can be used as a part datum by manually zeroing the X and Y feature coefficients. The X and Y coefficients can be zeroed in the DRO viewport or in the feature detail screen. To zero the X and Y coefficients of a feature: 1 Select (highlight) the desired feature in the Feature List. 2 Press the X coefficient button and then the Y coefficient button in the DRO viewport or in the feature detail screen. The X and Y values will become zero establishing the geometric center point of the feature as the part datum point. In this example, the geometric center point of circle 1 was set to zero and will serve as the part datum point for subsequent measurements.
