modify the selected lines or surfaces in GiD

[JayfansChou]

Dear all,

I'm Chou and I'm currently learning MPM by using GiD 16.0.6 and Anura3D 2023. Following the direction of offical document Tutorial manual 2023, I had a basic understanding of MPM and the usage of GiD. However, as with anyone learning new software, it's inevitable to make mistakes with my mouse clicks — selecting the wrong line or surface, and at this time I tried to correct these selections without changing their assigned names, it seems like it's unsuccessful, so I had to unassign the group and reselect it angin. Honestly, it's quite time-consuming. I'm curious to know if there's another way to adjust these selections without restarting from scratch. In ABAQUS, for instance, it is easier to modify the selected geometry. Is there a similar feature or technique in GiD that I might have missed? I'd appreciate it for your help.
