At the Ft. Worth Best In Graphics show last weekend, I saw a demo of ModelMill 3D CAD/CAM software (www.modelmill.com). I brought home one of their CD demos and am very impressed with the apparent power and user friendliness of the program. Two or three CNC router manufacturers at the show were using it and it was even recommended to me by a salesman for one of its competitors. So I'm seriously considering paying the (gulp) $3,000 that it sells for. I'm a sign maker and have been using LetterArt, CorelDRAW, and Arts & Letters for many years, but have never worked with any true 3D CAD/CAM programs. I'd like to hear from any ShopBotters who have any experience using ModelMill on their ShopBot or who have found any comparable program that is good for signmaking on a ShopBot.
