Hi There,

 

I am having a problem to define the CAD data coordinate system, Somebody please help and

one more thing is, it seems like my cad data have no projection as when i uploaded the data in ArcMap

a warning window popped out saying that "The following data sources you added are missing spatial reference

information. This data can be drawn in ArcMap, but cannot be projected.

Thanks Dan and I think you're right, but I managed to solve this by using georeferencing tools where I used the control points to define the projection of the CAD data.
