Hello Everyone,

I am quite a novice, extreme novice in dealing with the program ArcMap.

I am a architecture student trying to export editable contours from a USGS topography .tiff map to Autocad.

The topography is of Queens, New york, however I am not sure if I need a .shp file or drg or dem map of Queens first to extract
the contours. ( I am going of tutorials). Right now, what I have is the .tiff files of a raster image of topo of Queens however, when

I try to 3D Analyst > Raster Surface > Contour, a window pops up stating I do not have license to the tools. ( I am using the 60
days free trial).

Can anyone explain to me what I am doing wrong ? or what steps to take to find this information?
