Align Tool
The alignment tool can help you best position related objects. You can center or line up object along the standard X, Y, and Z axis. You can expand this function by combining the workplane tool with the alignment tool in TinkerCAD.
Task A (alignment with locked objects)
Using this TinkerCAD file as a starting point, use only the align tool to position the green spheres into their correct position.
Task B (Referenced Alignment)
Try to reproduce the animation below in your own TinkerCAD workspace.
To align two objects together, select them both, press the align icon (or use the L key) and you’ll be able to choose the nodes the two objects can mutually align to. Clicking on one of these nodes will move both of the selected objects to a new, aligned location.
But what if you don’t want both of your objects to move? Fortunately, it’s also possible to move one object into alignment with an object that remains stationary. This is called aligning to a reference, and it requires just one extra step.
To align to reference, select two or more objects to be aligned, press the align icon (or use the L key), then select the object you’d like to use as a reference. You’ll see that the alignment nodes now only appear around the reference object, which stays in place while the other objects align to it.
Task C (Shared Alignment)
Use the TinkerCAD document to align the provided rings into a single Tower of Hanoi.
