LANDXMLIN — Import LandXML

Imports the surfaces and points of a LandXML file.

• Command: LANDXMLIN · Global name: _LANDXMLIN
• Ribbon: Topography › Terrain data

Imports a LandXML 1.2 file, the exchange format of Civil 3D, MDT/TcpMDT, BricsCAD Civil and many field data collectors: each TIN surface is created as a surface (like SURFACE) and each COGO point (CgPoint) as a point object.

Usage

1. Enter LANDXMLIN or click Import LandXML in the Terrain data panel of the Topography tab.

LandXML file:

2. Choose the .xml file. Surfaces and points are created on the current layer.

Notes

• LandXML stores coordinates as northing, easting, elevation; LinceCAD places them as X = easting, Y = northing.
• If the file states its coordinate system (epsgCode) and the drawing has none, the drawing adopts it; if the drawing has another, the data are reprojected.
• Faces marked invisible (outside the boundary) are not imported; four-vertex faces are split into two triangles.
• A DWG face mesh holds at most 32,767 vertices: a larger surface is skipped with a warning.
• Surfaces and points are imported; alignments, profiles and parcels are ignored for now. Points arrive as point objects, without their name or code.
• Metric units are assumed.
