Do you need Designer 3 to use this (3d pattern modeling suite) ? I have 1.87. I went to the shopping cart on carvewright and it does not say. Just a hint for Carvewright. Each of the add on software pages on the store should say what versions of designer they work with and what additional software will be needed to use the software. With all the versions and add ons it is hard to decipher this. There is no "requirements" sections. I would hate to see someone buy this or other software and find out it would not work with the version of designer they have.
