The CAE (Datamine) Studio Export tool (on Discover's Export menu) is a simple and effective wizard that:

• Supports all MapInfo Pro vector, raster and (topography) surface data.
• Bulk exports your datasets in one routine.
• Reprojects all the data into the required (cartesian) projection.
• Allows the removal of unnecessary data fields (to help minimise output file sizes).
  
• Truncates and converts your data fields/columns to fit in Datamine Studio's restrictions

To import a Datamine wireframe model (*.dm file) into Discover, requires a Discover3D license. This can be done by either -

• Drag and drop into the 3D window
• File>Open>All Support Vector formats
• Or import into a Feature database, using Features>Import (which allows for further conversion to other formats).

Note Datamine files (*.dm) can be many different data types, including vectors (strings/polylines & points), wireframe/TIN models, Block/Voxel model.
