A forward construction method for designing pipe support and hanger models

This invention discloses a forward construction method for designing pipe support and hanger models. The method involves constructing a component family, which is a parameterized family of components that make up pipe support and hanger models with different structural forms. A pipe model is constructed, and the centerline of the pipe model is identified using Dynamo software. Based on the centerline, the placement point group of the centerline is analyzed using Dynamo software, and the parameterized component families in the component family are retrieved. Based on the placement point group, various component families are placed sequentially on the pipe to obtain the pipe support and hanger model. The beneficial effect of this invention is that by establishing parameterized families of components that make up pipe support and hanger models with different structural forms, and combining these families with the Dynamo software platform, the method directly calls the component families required by the model to be built for combination, thereby improving the speed and efficiency of pipe support and hanger model construction.
