Hi guys!
Hope this is not too late, but there are several AutoLISP programs/scripts out there that do the job just as desired:
A very versatile Point Manager Program from Lee Mac: http://www.lee-mac.com/ptmanager.html
A point import tool with various options (options are kinda tricky - one hast to edit the code in Notepad): http://www.hawsedc.com/gnu/pointsin.php
Another point import tool with many options (eg. insert a block with point attributes): http://www.jefferypsanders.com/autolisp_IMPORTXYZ.html
And finally one of my favourites, yet another point import tool and a point block with attributes:
The AutoLISP: http://www.cadforum.cz/cadforum_en/download.asp?fileID=613
The block: http://www.cadforum.cz/catalog_en/block.asp?blk=8520
The tutorial: http://www.cadforum.cz/cadforum_en/import-a-xyz-coordinate-file-as-autocad-points-with-labels-tip8496
Hope it helps you and any future user post.
