Hi Solidworks community,

I have a problem with datums in SW 2011, after a datum is inserted (attached to a dimmension) I can not select it, and if I update the drawing it dissapears, the only way to bring it back is moving the dimmensions from wich is attached, it appears again but there is no way to select it. If the dimmension was attached to a feature like a plane, forget it, it dissapear, but if I try to insert a new one I cant because SW tells me that is a datum already there, I have even reboot the PC but I have the same problem.

Thanks in advance for your help
