BIM technology-based tunnel gas pipeline construction process simulation method

The invention discloses a BIM technology-based tunnel gas pipeline construction process simulation method and relates to the technical field of building information models. The method comprises the following steps of (1) modeling through revit; (2) establishing a pipeline model; (3) establishing a support family model; (4) establishing a component model; (5) importing 3dsmax software; (6) baking the model; and (7) outputting a construction process simulation animation. According to the method, professional rendering software 3dsmax is used for replacing original BIM software Navisworks to manufacture the construction process simulation animation, the display effect is obviously improved, digital-analog separation data are integrated through component coding, the model reuse rate is increased, the reuse range is wide, and more BIM applications can be expanded for the rendered model. 本发明公开了一种基于BIM技术的隧道中燃气管道施工工艺模拟方法，涉及建筑信息模型技术领域，所述方法包括如下步骤：(1)通过revit建模；(2)建立管道模型；(3)建立支座族模模型；(4)建立构件模型；(5)导入3dsmax软件；(6)模型烘焙；(7)输出施
