B | 中国3D　CAD2025年份额排名前列的包括达索系统、西门子、PTC、中望软件等。　　业内人士分析称，国产CAD正在实现从“单点工具替代”向“全链路价值创造”的进阶。此次报告中，本土企业中望软件首次跻身中国市场全球品牌前三，意味着国产CAD逐步从追赶走向超越。　　“2025年，中国CAD市场在AI驱动下延续增长，国产厂商从2D替代向3D核心能力、行业场景和全球化验证拓展。”IDC中国制造业行业研究高级研究经理杜雁泽分析说，市场竞争焦点正从授权价格转向可量化效率提升、数据贯通和AI原生能力。　　底层几何内核被誉为工业软件的“心脏”，决定着产品能力上限。今年4月，经过长期打磨与百万级用户验证的几何内核overdrive®正式对外商业化，国产工业软件“在别人地基上盖房”的历史得以改写。　　另据介绍，新版本的3D悟空搭载了重构的新一代参数化设计引擎，上千步特征模型的改型刷新时间从过去的10分钟大幅缩短至1分钟。研发团队表示，以往需要20分钟才能完成的工程图关联更新，“现在仅需3至5秒”。　　技术成色还需由产业现场落地检验。据悉，经过中船动力、江淮汽车、创维、联想等多个龙头企业的应用验证，中国3D软件也实现从“能用”向“好用”的实质性迈进。　　有观察认为，当前，中国工业软件站在关键的转折路口。

C | 在国家政策支持、产业数字化转型加速、国产替代推进的多重利好下，CAD行业面临广阔发展空间。云端协同、AI赋能、应用场景拓展将成为核心驱动力。　　同时，行业竞争加剧、人才缺口、核心技术短板等挑战，亦需产业链各方持续投入与突破。
