I need to delete 1 million points

I have a drawing where I inserted +1 million points from a LIDAR survey a while ago, but now I want them gone. (yes, I know, I should have used data shortcuts). How can I delete these points/ all points?

Cliff,
How you delete them will depend on how you inserted them. Points from a LAS file, XYZ file? Details please.

To add to what @Pointdump said. You have a couple options. If using recap, I'd reduce density to about 70%. If you have a laz file. There are some really cool tools in the app store and there free Lidar tools for doing the weeding. HTH

One option is to use wblock and write everything EXCEPT points to a new file. Another is to start a new file and use Map Query to import everything except points. Of course if there are a lot of C3D objects and DREF's involved, these methods will have issues.
