I used the method of intersections to create an opening in a circular cylindrical wall surface.
How can I hide these auxiliary surfaces to create an intersection?
When creating an intersection, components are created in addition to the actual surfaces, which, for example, represent the intersecting pipes.
After generating the intersection, all components are at first activated. You can see this in the Data navigator under the entry for the surfaces.
Then, you can deactivate individual components. To do this, right-click the corresponding entry in the navigator or the component in the model. Now you can select the "Deactivate Component" option in the context menu. Alternatively, you can deactivate it by clearing the selection in the "Component" tab of the "Edit Surface" dialog box.
