Syntax
Parameters.IsExpressionValid( Expression As String, UnitsSpecifier As Variant ) As BooleanParameters
| Name | Type | Description |
| Expression | String | Input String value that specifies the equation. This string is evaluated the same way as strings entered in any of the Inventor dialogs are evaluated. For example '3 in + 2 cm' is a valid string for input. |
| UnitsSpecifier | Variant | Input value that specifies the type of unit the expression should be evaluated. 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. If the expression does specify a unit type, it should match the unit type specified by the UnitsSpecifier otherwise an error will occur. |
