Back when you were young (in BYs*) you learned that to move an object along the global X axis you would hit G, then X. And the same with all the other axes and transformations. But suppose you want to move an object along both the Y, and the X axes at the same time. Though it might not be readily visible that it’s possible in blender, it is, and there’s two ways to go about doing it:
1) If you are using hotkeys, select your transform type (G[rab]-R[otate]-S[cale]) then hit SHIFT-[The Axis you don’t want to use]. For example, let’s say you want to move you object along the X, and the Y axes. To accomplish that, you would hit G-Shift-Z. The result is that you lock the Z axes and have free movement along the X and Y axis.
2) If you are using the transform widgets in Blender, you would do something very similar to method one. All you do is Shift-Select the axes you want to lock.
I hope at least a few people found this helpful. I know that many people already knew about this little trick, but it doesn’t hurt to mention it, does it?
