I'm trying to write a script for attaching some objects together, I have to scan my main model(ground) split it to grid like quads of 250 for example check for each quad whether I have on it some objects (let say buildings), if I do have, I need to attach them to one object. Because I'm new at this environment I need a list of commands, function that can help me do it. Also if there are examples of some similar scripts, tutorials and other stuff it would be great. I'm using 3dsmax 5 with MAXScript. Thanks in advance.
