arXiv:2604.04050v2 Announce Type: replace-cross Abstract: Flow-matching methods for 3D shape assembly learn point-wise velocity fields that transport parts toward assembled configurations, yet they receive no explicit guidance about which cross-part interactions should drive the motion. We introduce TORA, a topology-first representation alignment framework that distills relational structure from a frozen pretrained 3D encoder into the flow-matching backbone during training. We first realize this via simple instantiation, token-wise cosine matching, which injects the learned geometric descripto
Advances in 3D reconstruction and AI are enabling more sophisticated methods for understanding and manipulating physical objects, making this research timely for practical applications.
This development indicates significant progress in AI's ability to interpret and assemble complex 3D structures, which is crucial for robotics, manufacturing, and design automation.
The explicit guidance provided by TORA's topology-first approach could make 3D shape assembly more robust and efficient, improving AI's capacity for spatial reasoning and manipulation.

AI models will become more adept at physically assembling complex objects from disparate parts.
This capability could accelerate the development and deployment of advanced manufacturing and autonomous construction systems.
It might lead to new design paradigms where products are optimized for AI-driven assembly, potentially transforming supply chains and industrial design workflows.
