Welcome to your new Trimble Quantm Help!
Rail alignments can be imported using the LandXML format to represent earthworks and derive earthwork volumes and mass haul. This is particularly useful when comparing design alignments to a design model to identify where any changes may have occurred and, also for conflict resolution in regard to earthworks for projects.
Before importing a reference alignment for earthwork comparison in Quantm the user will have to import the DTM. See Quantm Projects for importing and creating projects.
Note: How Quantm generates the models: if a TIN model is used to generate the reference surface in Quantm there could be a risk of some differences between the TIN and the grid surface created in Quantm. This may appear in the earthwork comparisons.
