Name As String,
Expression As String,
UnitsSpecifier As Variant ) As

Parameters
| Name |
String |
Input String value that specifies the name for the parameter. The name must be unique with respect to all other parameters in this document. If a unique name is not specified an error will occur. |
| Expression |
String |
Input String value that specifies the equation for the parameter. This string is evaluated the same way as strings entered in any of the Autodesk Inventor dialogs are evaluated. For example "x + 3 in / 2 cm" is a valid string for input. |
| UnitsSpecifier |
Variant |
Input value that specifies the type of unit the parameter is. The units can be specified using either a string defining a valid unit or an item from the UnitsTypeEnum. If the equation references existing parameters, this unit type must be consistent with the unit type defined by the equation, otherwise an error will occur. You specify a unit type using a value from UnitsTypeEnum or a string that describes a unit. For example, both of the following are valid unit specifiers for inch: kInchLengthUnits and "in". String specifiers are typically used for units that are not defined in the enum list. For example, the volume measure for cubic inches is not defined in the enum list but you can specify it using the string "in in in". |
Samples
