Rotade3D / 3DDrehen

Hi,

we are using the Draftsight Enterprise Edition at our Company. The language is german. We tried to rotate an existing AutoCAD 3D part (.dwg) with the command "Rotate3D" (which is in german "3DDrehen). When we type in this command in the command line, we get "Unkown command" as an answer. What is wrong? Do we have to adjust something in the Options? The command is exactly typed as in the help-file.

Any ideas what's going wrong?

Thanks in advance
