I added an opening to a curved quadrangle surface. However, only the boundary is displayed and the opening itself is missing. What went wrong?
In the case of quadrangle surfaces, the automatic object detection is deactivated. However, you can still integrate openings and other objects. For this, open the "Edit Surface" dialog box, "Integrated" tab. Click the "Integrate All Objects" button to display all nodes, lines, and openings that can be integrated. You can also select the objects manually.
