Hi Ben,

you could try also the following to get faces quickly. Simply save the point file with an .asc extension and then load it into Meshlab and in the "Remeshing, etc." menu apply ball pivoting surface reconstruction. Then save as .obj and use Michael's new Obj23dmWireframe converter with the new option and voila you can create quickly a surface for your sphere/dome or make a solid out of it.

Regards
Stefan
