Im sorry, that wasnt quite correct.
Peters macro does create curves but the are made by connecting the given points linear. So its not like a nice smooth curve like SW does it, e.g. in my picture.
I think you want to use the Curve Through Reference Points or Curve Through XYZ Points feature in SolidWorks. You would import the points from Excel. I've never done it but, you can probably search in the forums to find more information on the features. Or search the Help in SolidWorks.
Speaking of searching Help, to find out your serial number, select Help/About SolidWorks.
