Method for preventing IFC-format circular tube model from being imported into Microstation software to cause linearization

The invention relates to a method for preventing an IFC-format circular tube model from being imported into Microstation software to cause linearization. The circular tube model comprises a folded circular tube model and a straight circular tube model; the method comprises the following steps: pre-processing a folded circular tube model or post-processing an IFC format exported after a straight circular tube model is created; importing the processed circular tube model into Microstation software, so that the linearization of the model can be avoided; by the adoption of the method, boundary lines and construction lines appearing in the blanking view when the round tube model is imported into Microstation software in an IFC format can be eliminated, a concise model view is obtained, and a more friendly display effect is provided for follow-up model application. 本发明涉及一种避免IFC格式圆管模型导入Microstation软件出现线面化的方法，圆管模型包括折圆管模型和直圆管模型；通过对折圆管模型预处理或对直圆管模型创建后导出的IFC格式后处理，再将处理后的圆管模型导入Microstation软件即可避免模型线面化，采用本方法可消除圆管模型通过IFC格式导入M
