Yes they have come out with a new sp3 service pack for Civil 3D 2010.  But the bad news is that if you have installed the SAP you will need to uninstall C3D 2010, apply the new SP3 and then download the newer version of the SAP (that no one had any idea was new) and then install it.


So if you have a lot of machines in your office al they all have the SAP install then I would suggest reading the readme file (by the way the readme file has the install process backwards) to see if there are any fixes that are really important to you to want you to go through this huge headace!

But I would first read this thread on the SP3 install issues.
