pat totally understand your comments....the upgrade fees are not the problem....it's the usability of the 3d tools which are great but I am always looking for more, my work is on a professional level..... I have been using vw for the past 18 years
and have always upgraded and to know there has always been sufficient improvements to warrant the fees.....all I ask from my suppliers is to let me have some idea of their plans or improvements so i the client can make a judgement for myself instead of waiting for the updated version only to be ecstatic or disappointed in my decision.......but i thank you for your valued advice so i am just on my way to the hardware store to upgrade my hammer to version 18.....
