Understanding Each Tool’s Purpose

Araeo: Detailed Model Automation

Araeo focuses on automating time-consuming tasks within detailed architectural models. Once you have a Revit project with walls, doors, windows, and systems, Araeo helps you manage parameters, organize elements, and maintain model quality efficiently.

Typical tasks: Renaming elements consistently, updating parameters across hundreds of components, organizing families, standardizing annotations, and cleaning up model inconsistencies.

User profile: Architectural teams working on design development, construction documents, and BIM coordination. Serves designers who want to focus on design rather than repetitive model management.

TestFit: Site Planning and Feasibility

TestFit specializes in generative site planning and building layout optimization. It helps architects and developers quickly test multiple configurations of buildings on sites, optimizing for factors like unit count, parking requirements, and zoning constraints.

Typical tasks: Generating multiple site plan options, testing unit mixes, optimizing for maximum density, validating parking requirements, and creating feasibility studies.

User profile: Real estate developers, architects doing early-stage planning, and teams focused on multifamily residential or mixed-use projects requiring density optimization.

Using Both Tools Together

Integrated Workflow Strategy

Many successful architectural practices use both tools strategically throughout their design process. TestFit validates concepts early, while Araeo accelerates detailed execution later.

Example: Multifamily Project Workflow

  1. Week 1-2: Use TestFit to explore site options, test unit mixes, validate parking requirements
  2. Week 3-4: Present TestFit options to client, select preferred scheme for development
  3. Week 5+: Develop detailed Revit model, use Araeo to automate repetitive tasks
  4. Throughout: Araeo handles parameter updates, model organization, and documentation

Frequently Asked Questions

”Can TestFit replace the need for detailed Revit modeling?”

No – TestFit generates DXF files for early-stage planning, while detailed models require full BIM capabilities. TestFit helps validate concepts, but production work still requires tools like Revit and automation solutions like Araeo.

”Does Araeo help with site planning like TestFit?”

No – Araeo focuses on automating tasks within existing models, not generating site layouts or building configurations. For site planning and feasibility studies, TestFit is purpose-built for that need.

”Which tool provides better ROI for small firms?”

Araeo typically provides better immediate ROI for small firms due to zero cost and broad applicability. TestFit’s value depends on project types – essential for multifamily developers, but less valuable for custom residential or institutional work.

”Can I export TestFit results to Revit for Araeo to work with?”

TestFit exports DXF files that can be imported into CAD programs. While not direct Revit integration, you can use TestFit layouts as underlays for Revit modeling, then apply Araeo automation to the resulting detailed model.

”What about learning curves – which is easier to adopt?”

Araeo has a much shorter learning curve (minutes to hours) compared to TestFit (days to weeks). TestFit requires understanding of development principles and site planning concepts, while Araeo works with existing Revit knowledge.

Our Recommendation: Strategic Tool Selection

Different Tools for Different Phases

Rather than choosing one over the other, consider these tools as serving different but complementary phases of architectural work. The best approach depends on your practice type and project mix.

For Most Architectural Practices: Start with Araeo

Add TestFit If: Development-Focused Practice

Bottom line: These tools solve different problems at different project phases. Araeo should be in every architect’s toolkit for its universal applicability and zero cost. TestFit adds value for specific practice types and project phases, but isn’t essential for all architectural work.
