Renga Professional allows architects to create conceptual prototype of a future building and easily modify it depending on the customer’s wishes. Thorough elaboration of the future buildings' interior and exterior in 3D allows architects to make the right space-planning decisions, adopt rational structural concepts, design apartment floor plans and accurately calculate materials for project. Textures assigned to architectural elements help to render the future buildings, and, if necessary, speed up the process of generating photorealistic illustrations.

3D visualization allows adopting the right structural concepts and properly refining the nodes and joints of structural elements. To make the building more reliable, models created in Renga Professional have all the necessary data that can be transfered to structural analysis software. Renga easily integrates with structural analysis software solutions, which provides designers with the ability to quickly calculate building model, and make the calculation results the basis for filling and detailing of structural elements. Compared to Renga Standard, the list of structural analysis software solutions used in Renga Professional is longer due to the ability to exchange data via the IFC format..

To ensure human vitality in a building, Renga Professional has efficient tools for designing MEP building systems, including water supply and sewerage system, heating, ventilation, electrical and low current networks. This capabilities vastly improve the workflow for structural analysis and contribute to designers' ability to create information that captures design intent more efficiently and intuitively. Renga offers many available ready-to-use BIM catalogs that allow engineers to design MEP systems quickly and without struggle. And STDL scripting language, implemented exclusively in Renga Professional, makes it possible to create new categories of engineering equipment.

Making the right space-planning decisions, adopting rational structural concepts and capturing design intent in 3D model allow for automatically generated drawing documentation to unveil and amend errors. This functionality is an incredible time-saver that simplifies documentation workflow and improves design experience.

In order to solve additional tasks involving third-party software, for example, developing a plot plan or designing external utility networks, Renga Professional allows specialists to interact using the IFC exchange data format. In addition, the IFC format allows designers to prepare models for expert evaluation and meet customer’s requirements. Renga Professional supports many other formats including C3D, DWG/DXF, Stereolithography, OBJ, 3Ds Max, LightWave, COLLADA, FBX and VRML, CSV, RTB, RTS, PDF and OXPS.

To provide all project team members with the ability to work simultaneously on the project, Renga BIM software comes with the collaboration functionality, which is available only in Renga Professional edition. It allows several designers to create and adjust a digital building information model in real time mode. This functionality provides project team members with the important up-to-date information at any given moment, which significantly shortens design approval cycle and minimizes the probability of human error
