Choosing between two BIM architectural design software with similar goals—ArchiCAD and Revit—can be challenging. Many users compare them based on ease of use, available features, and other factors. However, one often overlooked aspect is software interactivity. So, which software offers better interactivity: ArchiCAD or Revit?
Open BIM vs. Closed BIM
Open BIM uses open data formats for software components, allowing these models to be read seamlessly by other related software without losing data. ArchiCAD emphasizes lightweight BIM with a smaller software footprint, differing from Revit in terms of functional variety. This focus gives ArchiCAD strong information exchange capabilities and promotes coordination across multiple software platforms. ArchiCAD models use the IFC format, which is supported by approximately 50 software programs that comply with open BIM standards.
ArchiCAD enables smooth data exchange with modeling tools like Rhino, the parametric design plugin Grasshopper, rendering software Enscape, animation and simulation software Cinema 4D, structural design software Tekla, and many others. This broad compatibility meets the needs of full-process BIM applications through open BIM integration.
On the other hand, Closed BIM refers to software ecosystems developed by a single vendor for the entire BIM workflow. Revit exemplifies closed BIM, using the RVT format to interact seamlessly with other Autodesk BIM tools such as FormIt for modeling, Navisworks for animation and simulation, Ecotect Analysis for environmental analysis, and CFD software.
Currently, ArchiCAD 25 supports hot linking with Revit. Models created in ArchiCAD can be saved directly in RVT format, or RFA family files can be imported as GDL objects for use within ArchiCAD’s object library.
Integration with Parametric Design Software
ArchiCAD utilizes the Grasshopper Live Connection plugin to enable interaction between the two platforms. Grasshopper’s parametric capabilities allow users to model complex shapes and surfaces or control building components parametrically through digital sliders linked to ArchiCAD modules.
Within the Revit environment, users can employ the Dynamo plugin for parametric design tasks. Dynamo helps automate repetitive tasks such as creating curtain wall units. Unlike Grasshopper, Dynamo focuses more on streamlining repetitive work rather than generating highly complex forms.
Interaction with Rendering Software
Revit aims to cover the entire BIM process within its own environment and includes a built-in rendering module for basic visualization needs. For higher quality renderings, users can leverage Autodesk’s cloud rendering service.
Both ArchiCAD and Revit integrate with Enscape for rendering, while Revit also supports Lumion through the Revit-to-Lumion Bridge plugin. In terms of image quality, Enscape and Lumion outperform Revit’s native rendering, which only satisfies basic requirements. Compared to Lumion, Enscape demands less from computer hardware and offers greater ease of use.
Both software platforms exhibit strong compatibility with external rendering tools, allowing users to pick the performance software that best suits their needs.
Integration with Analytical Software
Building performance analysis is a critical part of the BIM workflow. BIM technology addresses limitations of traditional design analysis by enabling quantifiable performance evaluation of building designs. Both ArchiCAD and Revit support building performance analysis through integration with specialized design analysis software.
ArchiCAD leverages open BIM principles and connects with Grasshopper via the Grasshopper ArchiCAD Live Connection plugin. It uses Grasshopper tools such as Ladybug, Honeybee, and CFD to analyze thermal performance and wind conditions of buildings.
