Select lone vertex, or specific polygons automatically

Is there a way to quickly select all the lone verticies in a mesh so I can delete them?

Part of my modeling approach is to use lone verticies as construction verticies, but they end up buried in the model. I want to remove them without using the Rem Doubles.

How about selecting all the polygons with n edges, such as “select all polygons with 5 edges”?

Thanks,

From the scripts window, select Scripts / Mesh / Clean Meshes. Select Vert: free or Edges: free etc

Great. Many thanks.

If the finished mesh will otherwise be a complete manifold, then ‘Select non-manifold’ (Cntl Alt Shift M) will select your construction vertices and lines.

Best wishes,
