Special Parametric Value (SPV)

 

MTT3D provides SPV for the user easily to access to important design parameters and modification. The list below introduces functionalities of SPV.

     SPV always exists and used internally.

     The existing common SPV is put in an input field of dialog box initially.

     If the user doesn't check the SPV name button and enter a numeric value in the input field of dialog, the system refers the numeric value.

     The user can create a new standard PV for the input field and its current value is the entered numeric value.

     If the user checks the SPV name button and enters a numeric value in the input field of dialog, the entered numeric value becomes the current value of SPV.
