Answer:
When you define line loads on a line that is decoupled from the entire structure, this line becomes semi-rigid. The program checks this incorrect entry and displays a message (Image 01). However, there are structures where this line is kept at a different point. In this case, the program continues with the calculation as soon as you confirm the message. However, since the deformation for such a decoupled line is very large, it is not displayed in the graphic output.
We generally recommend not loading lines that are decoupled using a line release or a line hinge.
The theoretical background is explained in this technical article.
