Editing a point cloud mesh

Hello, I have recently imported a .obj file into sketchup which is a mesh generated from Point Cloud data. The mesh has come in a 1 single surface. Is there a way of editing the surface?

View/Hidden geometry should show you what it is made of, if it is a group or component you will have to open it for editing to be able to edit it.
Double click will do that.
Other than that we can only guess without seeing the mesh.

Brilliant thankyou that’s done it!
