Standard Datums
Standard datums (datum axes, coordinate systems, curves, planes, and points) and their placement in the feature list can be verified. Use the following format in the start configuration file to set the standard datums:
[MODE]_DATUM_[ITEM] [item_name] [#]
where
• [MODE] is PRT or ASM.
• [ITEM] is AXIS, PLANE, CSYS, POINT, or CURVE.
• [item_name] is the name of the item. If the name of the item is not important, use the word NONE.
• [#] is the feature number. If only the feature name is important, you can omit the feature number.

In assemblies, the feature number is not the number assigned by Creo Parametric; it is the sequential feature number in the assembly, after ignoring skeleton parts if any.

For example,
PRT_DATUM_AXIS A_1
PRT_DATUM_PLANE DTM1 1
PRT_DATUM_PLANE DTM2 2
PRT_DATUM_PLANE DTM3 3
PRT_DATUM_CSYS NONE 4
ASM_DATUM_POINT PNT_1
ASM_DATUM_CURVE CURVE_1
ASM_DATUM_PLANE ADTM1 1
PRT_DATUM_PLANE DTM1 1
PRT_DATUM_PLANE DTM2 2
PRT_DATUM_PLANE DTM3 3
PRT_DATUM_CSYS NONE 4
ASM_DATUM_POINT PNT_1
ASM_DATUM_CURVE CURVE_1
ASM_DATUM_PLANE ADTM1 1
