How can I create a circular opening in a pipe?


Creating the opening by means of an intersection

To create the opening, you have to create a surface with the diameter of the opening through the pipe wall. With the "Create Intersection" function, you can create individual components that you can deactivate afterwards. The procedure is shown in the video.

Creating the opening by means of a converted intersection line

It is also possible to convert the found intersection line into a normal line. Then, the intersection can be deleted and an opening can be put into it. The inserted opening then has to be integrated manually into the surface (see the video). Please note, however, that the quality of an intersection is of a higher quality than the converted intersection line. When using the converted intersection line, discontinuities may occur in the rendering or FE mesh, depending on the model.
