I am trying to modify global variables within my C# code.

Based on these two examples:

Re: Macro change global variable

2015 SOLIDWORKS API Help - Add and Modify Equations Example (C#)

I have come up with the following code, but it doesn't change the global variables. Also, when I go into the equation manager after the code runs it has red Xs by the equations and says "The syntax of this equation is incorrect".

string Depth = "\"Depth\" = " + param["Part"].Substring(0, param["Part"].IndexOf("x"));

string flangeWidth = "\"FlangeWidth\" = " + param["Width"];

swEquationMgr = swModel.GetEquationMgr();

swEquationMgr.SetEquationAndConfigurationOption(0, Depth, (int)swInConfigurationOpts_e.swAllConfiguration, null);

swEquationMgr.SetEquationAndConfigurationOption(0, flangeWidth, (int)swInConfigurationOpts_e.swAllConfiguration, null);

NOTE: The Depth variable correctly evaluates to ("Depth" = 8) & flangeWidth evaluates to ("FlangeWidth" = 3.5).

Can anyone help me with what I am doing wrong?

Hi,

Make sure that you are using the correct decimal point. Try to set your param["Width"] to integer (e.g. 5) and see how it goes. What is the value inside param["Width"] and what is the type of the value?

Thanks,
