Robert, first of all you will need a 3D model to work with it in 3DS. 3DS accepts any method to describe 3D in DXF, i.e. by elevation, by 3D meshes, by polyface meshes – whatever you like. 3D meshes are used to describe faces with a rectangular topology, i.e. those that can be represented by n*m vertices. polyface meshes are used to describe faces using all other kinds of topology. 3DS uses polyface meshes for its DXF output, thus you can see that 3DS objects and polyface meshes fit together. I recommend that you have the firm either give you a DXF consisting of a polyface mesh of the island (at a reasonable resolution!) in Release 12 DXF format. If they work with AutoCAD Release 13, have them create a 3DS file directly (R13 has a 3DSout command). Dietmar
