The “Autogrid” toggle is another useful 3DS Max feature that a lot of users may not be aware of. In fact, it took me a while to realize its function while seeing it everyday, and I’m quite sure the same thing is true with so many long time users as well.
By using the “Autogrid” feature, 3DS Max will lock the gizmo and temporary grid of an object you want to create unto the surface of another object within your scene without intersecting and in the correct orientation of the objects faces. With this, you don’t need to rotate and align each individual objects which takes a lot of time especially if you are working in a large scene.
So here it is, just follow these simple steps.
1. Create any object in your scene. I deliberately used the Torus Knot to demonstrate how easy it is to use this toggle even on a complex shaped object.
2. Then choose the primitive object you wish to create and “check” or turn on the “Autogrid” option. This tells 3DS Max to identify the correct orientation of the object’s surface in relation to your target object every time you create one. If you try to hover your cursor over the target object, notice how it will adjust based on the surface of the object you hover it on.
3. And now, you are ready to add multiple objects in you scene. Notice how easy it is to randomly add objects anywhere without having to manually tweak each one. Imagine how much time you will save by using the “Autogrid” toggle in 3DS Max.
This function allows you to add very small details that will enhance the realism or you scene. Knowing this will save you a lot of time positioning objects to let you focus on more important stuff like texturing and lighting.
It can also be used on splines such as Text. Adding text to different surfaces can sometimes be a daunting task, but not with the help of this toggle.
