Currently, one of the mainstream BIM software solutions in China is Revit. It has gained widespread popularity among many enterprises due to its affordability and relatively gentle learning curve. Additionally, it is favored by numerous BIM professionals. However, over time, several issues with Revit’s usage have become apparent. Today, we will explore the challenges faced by Revit users in China.
1. Although Revit’s Building Information Modeling (BIM) capabilities are based on the international IFC standard and offer significant advantages in design, practical use is affected by discrepancies between international and domestic standards. In terms of BIM design technology, Revit is still developing, while its competitor, the 3D CAD product ArchiCAD from Graphisoft, holds certain advantages.
2. Revit’s 2D processing capabilities remain limited, showing a notable gap when compared to AutoCAD. The effectiveness of shortcut keys in Revit has also diminished. For users accustomed to AutoCAD, switching to Revit can feel unfamiliar. Tasks that require simple 2D illustrations, such as drawing a few lines, become unnecessarily complex 3D modeling processes in Revit.
3. During the early design stages, when many concepts are still vague, AutoCAD’s flat surface refinement often suffices. Revit, however, is primarily designed for construction drawings and quantity calculations. Using Revit to create mass models prematurely, although easy and not demanding dimensional precision, leads to problems as the project advances. Especially during preliminary design, expansion, and detailed construction phases, initial models often lack usable space and must be rebuilt. Furthermore, modifications to the initial models do not automatically update subsequent design drawings, resulting in wasted effort during conceptual design. For this reason, many design firms currently prefer using SketchUp for detailed 3D building modeling at early stages.
4. Although Revit includes rendering capabilities, these are far from matching the quality of 3ds Max. In China, most designs require high-quality renderings toward the project’s end. Many users hope to rely solely on Revit for rendering, but a combination of CAD, Tianzheng, and 3ds Max remains necessary—Revit alone cannot fulfill all rendering demands.
5. Revit’s drawing approach is based on “families,” which has both advantages and drawbacks. The family libraries are limited, requiring continuous downloading and updating. Missing components often have to be created manually by designers, which increases their workload significantly.
6. Revit usage is not limited to architects alone. If only architects use Revit, coordinating building drawings with other disciplines during construction becomes extremely inconvenient. Exporting CAD drawings and organizing them before issuing conditions is a critical step in multi-disciplinary coordination. With the release of Revit Structure and Revit Systems, efficient collaboration is possible only when all disciplines operate on the Revit platform.
In conclusion, Revit’s usage challenges in China remain quite evident. However, despite some shortcomings, Autodesk Revit’s design concepts are forward-thinking and represent the future direction of CAD (computer-aided architectural design). It is expected that Revit will continue to gain favor among architects moving forward.
