Embedded part and support hanger pre-matching method and system based on digital model

The invention provides an embedded part and support hanger pre-matching method and system based on a digital model. The method comprises the steps that arrangement information of embedded parts is obtained, and an embedded part model is established in the digital model; determining a to-be-associated support and hanger model, and matching the support and hanger model with the embedded part model to obtain a matching model; and carrying out deviation inspection on the embedded part in the matching model and the welding space of the support hanger corresponding to the embedded part. According to the embedded part and support hanger generating and matching method based on the digital model, whether the welding space requirement is met or not is judged by determining the contact area and the contact range of the support hanger and the surface of the embedded part, and therefore the design problem about the embedded part when the support hanger is installed is found in advance. 本发明提供一种基于数字化模型的预埋件和支吊架预匹配方法及系统，方法包括：
