The Workflow in 3D Modeling for Architecture After Conceptual Design

The process of transitioning from the conceptual design stage to detailed 3D modeling in architecture can be highly customized and depends on the specific project, client, studio, and individual design workflow. While some aspects of the workflow are automated, other steps require the expertise of human designers to ensure accuracy and creativity.

Automated vs. Manual Workflow

For projects that leverage Building Information Modeling (BIM), the workflow can be highly integrated and optimized. A typical BIM workflow may start with a schematic design using a software like ArchiCAD for massing studies, and then shift to more detailed models in software like Revit during the design development phase. Although both ArchiCAD and Revit are powerful tools, the true power of BIM lies in the integrated workflow, where models are exchanged and seamlessly integrated across different tools.

For example, if you are working with Formit for massing studies in ArchiCAD, the system can directly import or natively connect to Revit, allowing for the generation of more accurate early cost and area analyses. This integration ensures that as you make changes, you can see real-time updates in your models, making the design process more efficient and less error-prone.

Refining the Model in BIM

Once you have completed the schematic design (SD) and are satisfied with the massing studies, you can archive the model and begin refining it. The focus shifts from creating initial working views to developing more detailed printing views. This process can often result in having a significant portion of the construction documents (CD) already completed by the time you transition to the detailed design development phase.

At this stage, specific elements such as wall types are organized, and generic content is purged or converted into more detailed representations. Varying levels of 'real' content are set up with automatic generation of views and schedules. If the final deliverables require rich construction and owner data, the model will be refined further to include detailed construction data for use in the field or by the owners.

Working with In-House Design Departments

Some clients may have in-house design departments that work with software like SketchUp and AutoCAD for initial designs. These departments often send schematic design (SD) packages for feedback and further development. Once feedback is incorporated, these packages are sent for detailed design development (DD) where significant refinement is required to make the models permitable and ready for submission.

Architects like we do may use a site survey tool like Revit to build off initial SD packages or even link in landlord models for integrated design. This collaborative approach ensures that the design is not only visually appealing but also technically sound and feasible for construction.

Conclusion

While some parts of the 3D modeling workflow in architecture are automated, there are still many manual steps that require the expertise of designers. By leveraging tools like ArchiCAD, Revit, and Formit, the overall process can be streamlined, making the workflow more efficient and ensuring that the final design meets the client's requirements and is constructible.
