M3 Framework Database

All data relating to design, geometric and information modeling are stored in the M3 Framework Database managed by SierraSoft Rails.
The M3 Framework Database stores all the parameters and data of the project, geometric modeling, information modeling and information exchange.
SierraSoft Rails generates, starting from the data contained in the M3 Framework Database, all the necessary information documents and information models, with content and level of detail based on the requests.
The M3 Framework Database is the only reference for information and guarantees consistency between project data (plans, profiles, sections), information documents and information models.

Planimetría de trazado

Create horizontal and vertical alignments in a natural way

A system with a few essential commands allows to solve complicated cases in a natural way through grips, properties and intelligent objects.


The horizontal axis is defined through straights, circular curves, clothoid, parabolas.
Widenings and superelevations are automatically calculated during the geometry annotation.
Everything is displayed in real time, calculated and verified according to the set legislation.
The drawing of the geometry annotation plan is complete with all the dimensions of the various elements that make up the alignment.
The drawing is customizable thanks to the numerous dimensioning options available.

Longitudinal profile

The terrain profile is automatically returned based on your settings.
You can get profiles from different sources: 3D models, axes, sections, polylines, etc.

The project profile is defined with grade lines, circular curves, parabolic curves.
The graphic representation of the profile in the desired scales is complete with all the design elements.
Profile dimensioning is fully automated and customizable.

Typical sections and typical objects

Parametric and programmable for maximum efficiency and flexibility

Create and manage the typical section within a specific environment by assembling parametric objects included in the software or defined by the user.
Standard objects include roadways, layers, ditches, channels, walls, railway objects, generic objects.
The creation of the typical objects takes place in a dedicated environment.
You can parameterize features and data, and if that's not enough, you can program them using the included scripting language.

Secciones transversales

Automatic and always consistent with the information model

Extract all data wherever they are: from triangle models, from point clouds, from other axes, from information models (bridges, tunnels, ancillary works), from cartography.
The insertion and management of the project typical section takes place completely automatically on the basis of the data settings of the parametric design.
The drawing of the sections, completely customizable, includes the tables of quantities, the dimensions, the annotations box and the fills.

Quantities calculation

You decide what to calculate and how to calculate it

Extraction and calculation of quantities from different sources: sections, objects, surfaces, BIM entities, etc.
Definition of the quantities to be calculated (cut, fill, topsoil, etc.) based on the processes entered.
The results are stored within the information model and made available as printouts.


La libertad de proyectar donde quiera

Information and geometric modeling

Define your BIM model in detail

The information modeling takes place simultaneously with the design based on specific customizable settings.
The structure of the model, the elements that compose it, the geometric representation of the objects and their information content are defined.
Thus you create an information model according to the specifications required in the BEP.
The geometric information model is created while maintaining information consistency with all the information documents created.

Interoperability and multi-disciplinary integrated design

Share information models and manage federated models for road infrastructures

Share project information in IFC (3x2, 4x1, 4x3) and LandXML formats for export to other software such as Revit, Tekla, ArchiCAD, Trimble Connect, etc.
Import information models of ancillary works such as bridges, tunnels, art works for the integrated design and management of federated models.
