gmax provides tools that give you control over the positioning and alignment of objects in 3D space. With these tools, you can do the following:
Choose units from the most common real-world measuring systems or define your own.
Use the home grid as a construction plane, or use grid objects to position custom construction planes.
Select different options to align objects with grids, points, and normals.
Use 3D object snaps on a modeless dialog as you build and move geometry in your scene. Grid points and lines are among the many snap options.
Use "helper objects" in your work. Grid objects are in this category, along with objects used for positioning and measurement.
This section presents these brief topics designed to help you quickly start learning how to use the tools that make precision possible:
