I have several questions that i cant figure out in Maya 4.5: 1) How do i change the size of the grid? 2) how do i delete an object's history? 3) How do i link objects together? 4) how do i create an AABB? 5) how do i create a UVmap? im sure these are basic things to be answered, but i have 0 experience in modeling, and im sure i'll be having many many more questions.
