The Export LandXML TIN tool in the Project and Ground Classification tabs of the ribbon allows users to transfer surface data into downstream CAD workflows by creating LandXML files directly from LP360.

Export LandXML Settings
- Input Points Filter: Leverages the Live View dialogue to allow one to specify which points from your dataset will be included in the process. This filter can be customized to include or exclude points based on several criteria.
- Breakline enforcement: (*Introduced in v2025.2*) Used to modify the TIN (Triangulated Irregular Network) to ensure that linear features—like edges, ridges, or boundaries—are preserved by forcing triangle edges to align with specified breaklines. This prevents unwanted smoothing or triangulation across critical terrain features, maintaining accurate surface representation.
- Maximum Number of Points: controls the maximum number of points that will be included in the exported TIN (Triangulated Irregular Network) surface. This setting is crucial for managing the size and complexity of the exported file, especially when dealing with large datasets. By limiting the number of points, you can ensure that the resulting LandXML file remains manageable and compatible with downstream CAD applications.
- Output File: The export location and filename, where the default is "<LP360_Project_Path>\ActiveLASLayer.xml"
