Hi there,
I am updating some plate topologies from the Zahirovic et al., 2022 dataset to include new plate boundaries. However when I add the plate boundaries topology file to the project some of the lines from the feature geometries disappear, so I can’t add them to the revised topology. It’s only when I eject the topology file that the lines reappear…
Do you know why this may be the case? It happens in GPlates 2.3 and 2.5 on a Windows 64bit computer.
Thanks!
Alan

Hi Alan,
Try selecting `View > Geometry Visibility > Show Topological Sections` (see [here](https://www.gplates.org/docs/user-manual/Controlling_View/#35-geometry-visibility)).
It’s likely you loaded a project file that has it _unselected_. And it would be unselected because most users would only want to see the plate boundaries (and not the lines used to build them).

Ah of course, I should have picked up on that!
Thanks John
