ReliCAD: From Uncertain LLM Generation to Reliable Parametric CAD Modeling
Peng Zheng, Xintong Dong, Chuanyang Li +5
Large language models have shown considerable potential for natural-language-driven parametric CAD modeling. However, a fundamental contradiction exists between their probabilistic…

CopyCat: Improving Fine-Grained Subject Consistency in Subject-to-Image Models within Seconds
Peng Zheng, Ruiqi Liu, Rui Ma +1
Recent subject-to-image models have achieved impressive progress in personalized image generation, yet they still struggle to preserve fine-grained subject-specific details. A majo…

HistCAD: Constraint-Aware Parametric CAD Histories for Evaluating Editability
Xintong Dong, Chuanyang Li, Peng Zheng +5
Sketch constraints specify geometric conditions for constructing and modifying parametric CAD models. We study whether predicted constraints allow a given history to reproduce the…
