Development of one 3D cadastral certificate may take up to 2 weeks. Depending on the size of a building, the certificate can consist of over 20 standard charts, drawings and cross-sections. Engineers create them manually, which slows down the development of a cadastral certificate and increases the risk of errors.

At the request of a major Russian cadastral agency, Rubius has developed a system that generates a standard 3D certificate using a 2D drawing and object description. This method allows preparing a cadastral passport in just one day and helps avoid human errors.

The solution is based on AutoCAD, so there is no need for engineers to learn to use new software. They design drawings in a familiar environment and enter room details into a special form (dimensions, area, purpose, address, etc). Using this data, the system generates required charts, isometric projections and elevation views, and then compiles them into a finished cadastral certificate. 

System capabilities:

  • generation of apartment, section and floor plans
  • checking floor plans for errors during building construction
  • placing a 3D model on the planned landscape and verification of spatial coordinates
  • generation of isometric projections and elevation views of an object, and placing them on a certificate page in a specified scale
  • identification of geometric collisions
  • automatic apartment numbering
  • verification of the address and other object data using cadastral and other directories
  • checking room dimensions and types as well as window and doorway types for compliance with standards
  • registration of basement and attic rooms
  • generation of an object's cadastral certificate using the existing template
  • saving the certificate in one system, with the ability to track changes and assign access rights

The Rubius system has already been used to issue cadastral certificates for several complex infrastructural objects that can only be registered in 3D. One of them is the Floating bridge in Zaryadye Park, Moscow.
