Finely Register Error

[sak5098]

Hello Everyone,
I am trying to merge several point clouds to create a single model. I have roughly aligned two point clouds, and when I select the finely register two point clouds or meshes, I receive the error: "Select 2 point clouds or meshes!". Can someone please explain what I am doing wrong? Thanks in advance for everyone's help!

Yes, you have to select the entities (inside the 'folder' or 'group' entities that we can see on the capture). Each time you open a file, a 'group' entity is created, with all the 3D entities inside.
