Software version: 



You can insert LandXML reference models to Tekla Structures. The supported contents of LandXML files are terrain models, line alignments of roads and railways, and rain water systems.

You can export files in .xml format from applications like Bentley InRoads, Autodesk Civil, and Trimble Business Center, and insert the .xml files in Tekla Structures as reference models. The LandXML format extends the capabilities of Tekla Structures to show merged models, including the infra models. Tekla Structures supports LandXML 1.2 schema and single-precision floating-point format.

A typical example of a building structure where LandXML can be used is the surface of the bedrock to be utilized when pileslender column or pole that is put into the ground to carry loads or to provide support

Pile may be made of precast or cast-in-place concrete, or steel.

lengths are to be considered. LandXML can also be used when estimating the need of excavation. The LandXML format is important also for bridge and for civil structures design tasks.

An example of an imported LandXML reference modelmodel which the designer can use as an aid when building another model

A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.


An example of layers in a LandXML reference model:


The LandXML featurepart of Tekla Structures functionality that is maintained and owned by Trimble Solutions and that is included in the Tekla Structures installation

does not support all the possible data in the format. It supports the subset of the primitives defined in LandXML 1.2 schema, such as alignments, terrain models and pipe networks.

  • Surfaces are not shown correctly in drawings.
  • Triangle type of surfaces are only supported.
  • There is no warning if the LandXML file contains unsupported data.
