IGeom3DSurface

The IGeom3DSurface interface provides the basic information for a range of surface geometries. Through this interface you can get the type of surface, and by using the appropriate interface like IGeom3DCone, IGeom3DMesh, IGeom3DPlan, IGeom3DSphere, IGeom3DTorus, get more specific data about them.
