Coordinate systems

SierraSoft Land supports a wide range of coordinate systems, managing both EPSG standards-based systems and other localized systems.

This versatility enables users to work with geographic and projected coordinates according to recognized international coordinate systems, as well as to adapt to specific local needs, ensuring accuracy and consistency in design and information modeling activities.

Cross sections

Extract and manage sections of your 3D models

The sections can be automatically extracted either along a direction or along a polygonal alignment.
Through the extraction styles, you can extract complex sections using multiple 3D surfaces in one step.

Volumes

Calculate volumes with the best method

You can calculate volume with different methods, depending on your data and your goals.
The calculation can be done either using a model’s triangular surfaces or extracted sections.
The calculation for triangular surfaces is quite simple to use and extremely precise.

Calculate the filling volume of a basin.

Advanced information 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.

The integration of buildingSMART's IDS (Information Delivery Specifications) and bSDD (buildingSMART Data Dictionary) standards directly into parametric information modeling enables easy and intuitive creation, management, modification, and validation of information content, ensuring data consistency between project, information model, and information requirements.

Thus you create an information model according to the specifications required in the BIM Execution Plan (BEP).
The information model is created while maintaining information consistency with all the information documents created.

The activity of multidisciplinary collaboration is supported by the implementation of the BCF (BIM Collaboration Format) standard, facilitating both design integration and BIM collaboration.

Information analysis and verification

Analyze and verify the information content of BIM models

The analysis, verification and validation of information content occur simultaneously with the activities of design and information modeling. This aims to identify and resolve any design and modeling errors at the point of origin, where it costs least to resolve them.
Then so identify interferences between created models and between federated models, verify the structure, the elements and the information content. In addition to standard checks, specific checks are provided for topographic and infrastructural information models.
Requires the SierraSoft BIM Checking software extension.
