Hole Parameters
When you create a standard Hole feature, it includes the parameters listed in the following tables. These are read-only system parameters, whose values are taken from the hole chart. To add user-defined parameters to the hole chart, see Hole Charts.
Starting from Creo 10, you can add parameters to simple holes. These behave similarly to the parameters in standard holes.
You can view the parameters by right-clicking a hole in the Model Tree and choosing either

ECAD parameters in holes
When you create a Hole feature in ECAD, it includes the parameters listed below.
 | These parameters are not created for holes with a  Sketched profile, or for holes with placement type  Sketched. |
Additional parameters in ECAD holes | Description |
|---|---|
ECAD_ASSOCIATED_PART | In the ECAD system, this is the part to which the Creo Parametric hole feature relates. Can be edited on the Properties tab. |
ECAD_HOLE_OWNER | Owner of the hole feature, ECAD, MCAD, or UNOWNED. |
ECAD_HOLE_TYPE | The type of hole feature. If the hole is not imported as a feature, the parameter is not imported. Can be edited on the Properties tab. |
ECAD_PLATING_STYLE | Plated through hole, non-plated through hole. |
