It appears that a3d to stl conversion is related to a transformation of Amapi 3D models (.a3d) to STL format form 3D printing. For this you will need some dedicated 3D model converter, such as the 3D Object Converter that should allow you to convert a3d to stl just fine.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.

A3D
Files with a3d file extension can be found as 3D models from a long discontinued program called Amapi.
STL
Files with stl extension can be mainly found as stereolithography files for 3D printers. Used in many CAD programs as output format for models and prototypes that could be printed in stereolithography devices.
