Problem: There is no possibility to change shape healing options from DRAW without rewriting resource file. Change: Shape healing parameters from STEP and IGES resource files were duplicated to InterfaceStatic. Resource manager initialize from InterfaceStatic if resource file name is empty. Result: User can operationally change shape healing parameters from DRAW command using "param" command.
