Abstract
Design and Efficacy Verification of Low-Cost Digital Toolchain Based on SketchUp-ComfyUI Collaborative Workflow for Modern Functionalist Architecture
Incoming article date: 09.06.2025This paper proposes a low-cost digital toolchain based on SketchUp-ComfyUI collaborative workflow to validate its technical feasibility in modern Functionalist architectural design. The research establishes a tripartite methodology comprising "geometric modeling - parameter extraction - rendering verification": initially developing core parameters through fundamental geometric models (cubes, cylinders) in SketchUp, followed by constructing visual workflows via ComfyUI's nodular interface for Functionalist architectural rendering. Key findings demonstrate: (1) Total time expenditure for residential unit prototyping and rendering reaches 26 minutes, meeting rapid design requirements; (2) ComfyUI accurately recognizes SketchUp geometries through AI parametric control mechanisms, yet constrained by SD training data limitations (Functionalist cases constituting merely 12.7%), exhibiting 55% semantic hallucination rates in massing generation while enabling reverse-engineering analysis of rendering visual semantics; (3) This toolchain achieves zero-cost implementation on standard computing hardware, pioneering democratized design approaches for Functionalist architecture.
