How do I create a circular opening in a pipe?

Answer

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 function 'Create Intersection' single components are created which can be deactivated afterward. The procedure is demonstrated 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 must then be manually integrated into the surface (see video). However, it should be noted that the quality of an intersection is higher than the converted intersection line. When using the converted intersection line, discontinuities may occur in the rendering or in the FE mesh, depending on the model.
