.NET Syntax

Visual Basic (Declaration) 
Function Add3( _
   ByVal Index As System.Integer, _
   ByVal Equation As System.String, _
   ByVal Solve As System.Boolean, _
   ByVal WhichConfigurations As System.Integer, _
   ByVal ConfigNames As System.Object _
) As System.Integer
Visual Basic (Usage) 
Dim instance As IEquationMgr
Dim Index As System.Integer
Dim Equation As System.String
Dim Solve As System.Boolean
Dim WhichConfigurations As System.Integer
Dim ConfigNames As System.Object
Dim value As System.Integer
 
value = instance.Add3(Index, Equation, Solve, WhichConfigurations, ConfigNames)
C# 
System.int Add3( 
   System.int Index,
   System.string Equation,
   System.bool Solve,
   System.int WhichConfigurations,
   System.object ConfigNames
)
C++/CLI 
System.int Add3( 
&   System.int Index,
&   System.String^ Equation,
&   System.bool Solve,
&   System.int WhichConfigurations,
&   System.Object^ ConfigNames
) 

Parameters

Index
Index of the new equation (-1 places it at the end of the list)
Equation
String containing the equation (see Remarks)
Solve
True to solve the equation immediately; false to solve later (see Remarks)
WhichConfigurations
Configuration option as defined in swInConfigurationOpts_e (see Remarks)
ConfigNames
Array of the names of the configurations to which to add this equation; valid only if WhichConfigurations is set to swInConfigurationOpts_e.swSpecifyConfiguration, in which case, include the name of the current configuration in this array

Return Value

Index of the new equation if successfully added, -1 if error

Example

Remarks

This method only works for parts having multple configurations created in SolidWorks 2014 or later. Use this method to add dimension equations, component equations, or global variable assignments to various configurations of models. If you don't have multiple configurations, then call IEquationMgr::Add2, which does not support configurations and is slightly faster.

 

To add an equation using the SolidWorks user interface, you must embed the names of dimensions and global variables in double quotes: 

  

    • Global variable assignment:
      "B" = 2    
    • Component equation:
      "N_SPOKES@CirPattern" = "BARLENGTH@Sketch2" /10
    • Dimension equation that uses the Visual Basic IIf function:
      "D1@Extrude2" = (IIf("D1@Extrude3">20, 15, 6))+5
    • Dimension equation that sets a dimension to the current value:
      "D1@Extrude2" =    

NOTE: To add an equation using this method, you must specify Equation with the names of dimensions and global variables in double double quotes and the entire equation in double quotes. See the Examples.

You can add a dimension equation whose left-hand side already exists, but only if the existing equation is suppressed. Adding the equation again unsuppresses it. See IEquationMgr::ChangeSuppressionForAllConfigurations and IEquationMgr::ChangeSuppressionForConfiguration.

Setting Solve to false delays evaluation of this equation, which enhances performance when there are many equations to solve. When Solve is set to false, the equation appears in the FeatureManager design tree only after calling IEquationMgr::EvaluateAll or IModelDoc2::EditRebuild3.

When adding global variable assignments and component equations, WhichConfigurations must be set to swInConfigurationOpts_e.swAllConfiguration. 

If you add a global variable assignment that already exists, this method returns an error.

To modify an equation added by this method, call IEquationMgr::SetEquationAndConfigurationOption.
