This file format can be used to export data which can be subsequently imported into Lines within the Tribon/Aveva Marine Initial Design tool. Lines itself does not have the ability to import native geometry using a standard file format such as IGES. However, using this option, geometry can be exported and a close approximation regenerated from the Macro file in Lines using native geometry. Geometry defined in X-Topology is processed to ensure that there are data points that correspond to each curve intersection and tangent constraints are transfered.
