Can anyone point me to sketchup 5? Is there still a place to download it? I'm running an older mac, and I must assume that my processor is too slow for SU6. I assume because I cannot find any info on system requirements for mac. I do have OSX. I have been working with sketchup6 on a friend's pc and would like to get it at home, for modelling timberframing. thanks for the help if you have it. -mark in ontario, canada.
