Building Information Modeling: Why Renga?

Last Updated: December 17, 2025

When you begin your building information modeling journey, selecting the right software is crucial. Your future performance and comfort depend on it.
For businesses, the most significant software selection criteria are:

  • Integrated approach to design
  • A wide range of basic tools available out of the box
  • Convenient user interface, easy learning curve
  • Design automation tools
  • Collaboration capabilities, shared information resources
  • Project file size
  • Pricing policy

In this article, we will talk about the key design approaches that Renga BIM software offers. We will answer the question: how exactly does building modeling in Renga differ from other BIM solutions?

1. Integrated Projects

Renga is a comprehensive BIM system for designing buildings and structures of any complexity. The design deliverables include detailed information models of the architectural and structural components of the building, as well as engineering solutions and utilities. Renga’s Bim software is used throughout the entire project life cycle, from construction to operation and renovation.

The integrated design approach offers numerous benefits, the most significant being its ability to help avoid potential problems during the construction phase. Designers examine every detail to identify potential conflicts and resolve them before they become real-world problems. This saves time and money.

Besides, Renga’s integrated approach results in high-quality projects. Rendered 3D models convey the design concept as accurately as possible. 3D projects cover every aspect of construction to create functional and attractive buildings.

2. Real-Time Collaboration

Renga Bim software is an integrated product. Architects, structural engineers, and mechanical and utility engineers use this tool simultaneously. For this, Renga BIM software offers a unique Real-time Collaboration tool similar to Google Docs. All stakeholders work with the same model in real-time.

Each stakeholder can see the changes made by their colleagues. Such team collaboration helps avoid conflicts between the architectural concept, the design model, and utility networks. It also accelerates project development and review processes.

3. Intuitive User Interface

Most BIM systems use a Ribbon or Microsoft Fluent Interface- toolbars with tabs.

Renga has deviated from the ribbon approach to develop a more intuitive and minimalistic user interface. The graphite color palette ensures maximum visual comfort throughout the workday and does not distract the user from the 3D model. The panel layout and command logic result from long, extensive discussions and the study of vast amounts of professional literature on user interface design.

Today, many designers work with not one, but two, or even three monitors. It expands your workspace and makes it easier to compare documents and perform other tasks. Most CADs for the construction industry do not support the multi-monitor mode.

We believe using multiple monitors greatly enhances convenience, so we enabled Renga to drag and drop windows with views, drawings, tables, and BOMs between monitors or split a window in half on a single monitor. The models and views have two-way associativity: when you change a model, the views update, and vice versa. It makes it easier to review the changes.

According to user reports, the Renga modeling interface is simple and convenient, and the system is easy to master. It takes just a few days for designers to learn the basics and start their first projects.

4. Full-Fledged 3D

How do they build 3D models in most other commercially available solutions? From 2D sketches that are extruded into 3D. However, the extrusion height is poorly controlled, which can lead to errors. Sure, you can identify and fix such errors in the 3D model.

But why do double work? In Renga, the process is reversed: we start with a 3D scene and populate it with such objects as columns, beams, walls, foundations, etc. Such a 3D approach is no more difficult than the conventional 2D thanks to the context-oriented interface, convenient panel layout, and object snaps. Note that there are no limits: you can easily switch between 3D to 2D while making an integrated building or structure model.

5. No Libraries and Component Catalogs

Most CADs feature libraries and component catalogs. Each new size of a window, door, or beam must be included in the catalog. An architecture firm often discovers that many such components are neither included in the software, nor available online. Building a component model from scratch is time-consuming and requires parametric modeling and programming experts.

Renga has no such catalogs. Instead, it offers a so-called CAD in CAD or a system of styles. The new approach minimizes component modeling efforts and reduces the number of component instances. You can create your catalog to be independent from incomplete third-party databases. It takes just a few minutes: to adjust the parameters of a system object and create a new instance.

6. Design Automation

Renga provides extensive functionality for architectural, structural, engineering, and utilities design.

The smart 3d design tools make modeling easy and convenient, reducing overall project development time by automating routine operations. No need to draft floor plans, facades, and sections manually, to calculate BOMs and bills of quantities. All these are generated automatically from a 3D model and are associatively updated as the master model is changed.

Another excellent tool is the auto rebar placement feature in 3D. These tools significantly accelerate rebar placement in cast-in-place reinforced concrete components. You can add more rebars to openings in slabs and walls.

Another unique tool for utility engineers is called Auto Tracing. The tool automatically traces pipes, ducts, and cables, and connects equipment to them according to the user-defined rules.

7. Small Project Files

Renga’s other important advantage is the final file size. It is small even for a 30-story building project. Such a file can be quickly copied to a USB stick or emailed. How did we achieve this? The project file is an XML document, a plain text file containing a compact parametric definition of the objects, their relation location, and other information.

A major advantage of XML documents is that they are relatively simple to create and process, and contain well-structured, computer-friendly information. The 3D model is built from scratch as the file is opened. Moreover, such a logic does not slow down file opening. You can open even the most complicated projects in a few seconds.

8. 10+Supported Export/Import Formats

We realize that a building project may require using multiple specialized tools. To exchange information with other systems, Renga supports many file formats:

  • DWG, DXF, PDF, OXPS: drawings
  • CSV: properties and analysis data
  • 3DS, LWO, STL, OBJ, COLLADA, FBX, C3D, STEP, IGES, PARASOLID, ACIS, JT, and VRML: polygonal and solid models.

Renga also supports the Open BIM program for building information model exchange. It can import IFC4 files and convert models to IFC4.

IFC is an open data format developed by buildingSMART (International Alliance for Interoperability, IAI) for better interoperability in the construction industry. The IFC format is supported by many software developers.

The scope of data included in an IFC depends on the functionality of the software that would use this file. In Renga, you can configure the IFC export to meet specific requirements. for better interoperability.
