Difficulties of design solutions

[shamimhasan07]

Today, Russia has solutions such as Renga, Robur, and KREDO. However, their functionality is still limited, especially in terms of working with linear objects. At the same time, these software products have convenient options for detailing models (for example, breaking down point elements into separate structures).



Design of linear objects such as roads, utility networks and transport infrastructure is numeros de telefonos en colombia performed with high accuracy and detail. Civil 3D exports routes and profiles in IFC 4.3 format without serious problems, but there are limitations when modeling some utility networks.

Thus, the development of lighting and electrical network models causes difficulties due to the impossibility of specifying several rotation angles without breaking up the pipes. Also, the program does not allow for the correct modeling of some objects, such as lighting supports, due to the lack of their division into constituent elements (foundation, support, bracket, and lamp).

To model roads in Civil 3D, corridors are used, created on the basis of routes, profiles and cross-sections. Yaroslav Demichev noted that cross-sections often change, which complicates the design of urban roads. Because of this, it is necessary to use universal design elements, the creation of which takes a lot of time.

Another drawback is the limitations of the program's functionality for working with traffic management tasks. For example, road signs and traffic lights are formed in Revit and then integrated back into Civil 3D. Russian analogues provide more advanced tools for these purposes, which gives them significant advantages.

Data export formats
Export of digital models in IFC format has become the standard for providing data for state expertise. After the creation of the IFC 4.3 scheme, it became possible to take into account the features of linear objects. However, the data structure in the exported files still leaves much to be desired.

The BCF (BIM Collaboration Format) format is actively used for interaction with employees of state examination bodies. It allows working with comments directly in the model, which speeds up the process of their elimination. In Autodesk products, BCF is integrated using free plugins. But in Russian programs, according to Yaroslav Demichev's experience, importing this format is not yet possible.

It is impossible to make a clear choice
Yaroslav Demichev noted that digital information modeling is extremely useful for passing state examination. In the future, the development of domestic technologies and standardization of requirements will improve the efficiency of using BIM in Russia. But for now, there are a number of unresolved issues on the way to its implementation:

Lack of uniform standards for CIM in Russia
Limitations of software functionality, both imported and domestic
Insufficient development of examination requirements
Despite these problems, tools like Civil 3D and domestic analogues already allow designers to cover their basic needs. In practice, the examination mainly checks models for collisions and compliance with standard distances, which does not require high model detailing.
