It can be known that after the arc pipeline groups are built, before the primitive is called, primitive calling, primitive modification and primitive connection test can be performed on the primitives in the pipeline groups in the project environment.
It can be understood that the graph modification in the above test needs to check whether the parameter performance of the primitives is normal, whether the corresponding primitives are connected normally, and check the display and the performance of the visibility of the view, for example, the arc tube segment group, through repeated test and modification.

S302, connection of the graphic element, the connection accessory and other graphic elements is completed through the small curvature elbow, so that a pipeline system model is constructed.
It is understood that the connection accessories may include connection accessories such as a tee, a four-way, a big and small head, a valve, and the like, and connection between adjacent graphic elements, connection between the graphic elements and the connection accessories, and the like are all realized through a small curvature elbow.
