MIRAGE-CAD：通过构造中介的多模态可执行CAD程序生成
原标题：MIRAGE-CAD: Construction-Mediated Multimodal Generation of Executable CAD Programs
AI 摘要
MIRAGE-CAD 是一个多模态 CAD 程序生成系统，能从自然语言、图像、点云和 STEP/B-Rep 几何输入生成可执行的 Python CAD 代码，并通过 OpenCASCADE 内核执行。该系统引入显式的构造中间表示（IR）作为计划接口，实验表明该表示有助于提高生成程序的构建成功率和几何保真度，且其可读性为下游执行成功提供参考。研究还发现，可执行有效性、几何保真度和参数响应性可能显著不同，应分别评估。

MIRAGE-CAD: Construction-Mediated Multimodal Generation of Executable CAD Programs Abstract Recovering an executable parametric CAD program from an observed object is fundamentally ambiguous, because the same final geometry can result from different construction procedures. We study this problem from four types of input: natural-language descriptions, rendered images, point clouds, and STEP/B-Rep geometry. MIRAGE-CAD maps each input to a shared construction representation and mediates program ge
