With the diversified development of populace’s aesthetic, non-standard building form gradually gains popularity. The paper aims to explore the working process of non-standard building form from design sketches to digital model and physical model, which provides reference for related studies and engineering practices. The paper ifrst demonstrates the creation background of non-standard building form, and reviews the related works. Then, the paper proposes the design concept of the non-standard building form based on the design conditions. Furthermore, the study adopts digital model built in Revit to divide non-standard building form surface and completed physical modeling using laser machine cutting. The practice results show that the non-standard building form surface mesh have prominent effect on the smoothing level of form surface, and parametric modeling could efficiently promote the design efficiency and construction precision of non-standard building form. Hence, the designers should use parametric modeling and numerical control processing techniques in non-standard building form design, and improve the smoothness of the non-standard building form through editing the mesh division.%公众审美日趋多元，非标准建筑形态日渐增多。文章旨在探索非标准建筑形态由设计草图到数字模型再到物理模型的工作过程，为相关研究与工程实践提供参考。首先阐释了非标准建筑形态创作背景，归纳已有研究成果；再结合设计条件，提出非标准建筑形态设计概念；然后根据设计概念，应用Revit建立数字模型，展开非标准建筑形态曲面划分；最后应用激光切割设备完成非标准建筑形态曲面数控建造，建构物理模型。实践结果表明：非标准建筑形态曲面网格划分形式对曲面平滑程度有显著影响，参数化建模与数控加工技术的应用有效提升了非标准建筑形态设计效率和建造精度。因此，设计者应在非标准建筑形态设计与建造过程中引入参数化建模和数控加工技术，并通过调整曲面划分网格优化非标准建筑形态的平滑度。
