Hi Vipin, You can take a look to the .3dc plugin sources. Here the geometry is batched into chunks of 10.000 points, which is a well-working size for batching geometry as Chris said. If you spatialize your data correctly may be you don't have to use LOD techniques, it depends of the amount of data.
