Sorry you are having issues. What software are you trying to import the dwg drawings into? If you are using ArcMap 10 and later then the following should be of help.
Convert CAD Feature Layer opens the Copy Features tool
Convert CAD Feature Dataset opens the CAD To Geodatabase tool.
Convert to Geodatabase Annotation opens the Import CAD Annotation tool.
Alternatively you could use your existing CAD software and convert each layer in CAD to shapefile by using select by attributes then
export that data as a shapefile. As with all CAD drawings you will have to decide what geometry each output will have in the new shapefile format. For example,
an open ended Line, you would export as a polyline shapefile, a closed line would be a polygon shapefile and so on.
Hope that helps.
