Can we pass value as variable to enterpath function other than pathWidth

 Hi Roy,

 I'm not sure that I understand the question correctly. You want to pass a number to enterPath that is not for the path width argument? If so, what is this number for, what would it control or influence if not the path width?  Or are you asking if it is possible to use a variable for the pathWidth rather than a fixed numerical value?  In this case yes, a variable can certainly be used, for example:

 hi Lawrence,

         I was trying to create a bus structure program, for that I used  CCSslotMetal.il  pgm as blue print to accept width ,layer cyclic field and snap.In the main function which create a bus structure I wanted to control the number of wires to be accepted from user.So for this I tried sending that  through enterPath function.

But  CCSmetBusCB function through which I was sending the number (variablefor controlling no of wires). There was an error i CIW stating that variable should be a list type template.So can u help me out.

Below is my pgm ,which creates metalbus structure with 10 wires.
