Yes, you may have already heard about this being available, but I wanted just reiterate that the first Service Pack/Update for Navisworks (Manage, Simulate, Freedom) 2012 is available. You can download the update HERE. As usual, make sure you download the appropriate version for your OS (32bit vs 64bit).
Also, make sure you look at the available download links…there is a separate download for the NWC Exporters as well.
This is available for those of you who only have the Exporters installed, you don’t actually have Navisworks installed. If you have Navisworks installed and install the Navisworks update, you do not need to install the Exporter update as well…this is already in the Navisworks update package. See the comment below from Lee (Beyond Design blog) regarding the Exporter Update…I was slightly incorrect on the above comments about the Exporter Update.
“If you installed Navisworks Manage or Simulate 2012 or the standalone NWC Exporters prior to September 2011, then you should install the separate updated Exporters, this is NOT contained in the Service Pack.”
As for the list of updates, take a look at the PDF HERE.
