Hari, O.K., so back to your original example which has to do with a technique for placing a knurl on a cylindrical surface. If you want to follow the directions to do it yourself, click the link at the top which says "Download Example Files for this Technique". Save the files to some appropriate directory, unzip them, then follow the directions to learn the technique. If you also want to have finished files, representing the result of the technique, click the link at the bottom which says "Download Finished Files for this Technique". David
