Never used intralink we have only just started on implumenting Creo in the last year so still learning lots myself.
Have learned PTC is a funny company.... seems like they come up with good idea's take it just far enough to get people to start buying the itea then abandon it and move to the next idea..... and rather then recognize that there are more then one way to skin a cat and that customers might actually want to product nice drawings say like autocad can do they ignore or look down there noise at anything anyone else came up with....
honestly with what I know now if it wasnt for Creo's automation abilities I wouldnt use this software if PTC gave it out for free.....
doesnt make a nice drawing doesnt play well with plotters, doesnt work well without windchill, doesnt have good support from PTC just try to get ahold of them for support, finding any info on how to use alot of functionality is just about impossible almost like its a big secrete and only they may know.... gah.
well theres my rant of the day lol.
