My feedback from my users has always been Navisworks is more user friendly than Aveva Review. I come from a background of using Navisworks for reviewing and clash checking. My current employer uses Aveva Review and Clash Manager. So now that i have used both products i do find Navisworks more user friendly. I think a lot of the issues people are posting is they are not familiar with the software (no training or don't want to use the help files provided). Now that being said a lot of these issues have been addressed if only the forum user would do a search on it.
