You can think of the 3D Cursor tool in Blender as the center of the world you’re creating. The 3D Cursor is located in the 3D space you’re working in, and at first, you might just see it as the point where all new objects are 'spawned.'

However, there’s much more you can do with the 3D Cursor once you’ve mastered it. It’s an invaluable tool for modeling or animating, and this article serves as a mini Blender 3D Cursor tutorial, guiding you through the broader strokes of using this tool.

Section 1: Basics of the 3D Cursor

What is the 3D Cursor?

So, you want to know: what exactly is the 3D Cursor in Blender? You can think of it as a custom point in your world that can be used for a variety of tasks. Most notably, new objects are created wherever the 3D Cursor is positioned.

However, the 3D Cursor can also be used to pull vertices to specific spots, set a pivot point for objects, move objects or their vertices, and much more.

By default, you don’t need to do anything to set up the 3D Cursor. It’s always at the world origin to start, which is at coordinates 0,0,0. If you ever need to set the 3D cursor to 0 0 0 in Blender manually, simply reset it to the origin.

Navigating the 3D Cursor

Mastering Blender 3D Cursor starts with knowing how to move the 3D Cursor around. That’s not too tough, honestly. You can simply click the Cursor option in the Toolbar (second from the top) and click anywhere to place it. It’s best to do this with at least two orthographic views for precise placement.

Shortcuts in Blender are key, though, so you can also use the Shift + Right Mouse Button combo to place the 3D Cursor regardless of which tool you’re currently using. Shift + Spacebar, followed by Spacebar, will take you to the 3D Cursor tool too. To change the 3D cursor position in Blender, simply click in the desired location, or use the Shift + C shortcut to move the cursor to the center in Blender.

Section 2: Practical Applications

Modeling with the 3D Cursor

The origin of an object is at the center of that object by default. However, you might need to move its origin to another position for modeling purposes. You can instantly set an object’s origin to wherever the 3D Cursor is. Select the object, go to the Object menu in the top header, then Set Origin > Origin to 3D Cursor. You can also access this by right-clicking on the object.

This is cool because now the origin serves as the new pivot point for rotations, which can come in handy for many animation scenarios, like one object orbiting around another.

Aligning Objects

Want to align objects straight to where the 3D Cursor is? That’s incredibly easy. Place the 3D Cursor and then select the object you want to align. Press Shift + S to bring up the Snap menu and then choose “Selection to Cursor”.

Alternatively, you can right-click on the object you want to align, then choose Snap > Selection to Cursor. If you want to quickly align objects, simply place the Blender cursor to the center of the object using the Shift + S shortcut, which opens the Blender cursor menu.

However, it’s advisable to use this only when you’ve placed the 3D Cursor precisely. It’s best to do this from at least two orthographic views. You can access the front, side, and top orthographic views using Numpad 1, Numpad 3, and Numpad 7 respectively.

Adding New Objects

New objects will appear wherever the 3D Cursor is located. You can try it yourself by moving the 3D Cursor to a new spot, then going to the Object Mode header, choosing Add, and creating any object there. Learning UV mapping is also a good idea to make those objects look even better.

Section 3: Advanced Techniques

Custom Transformations

One of the best Blender modeling tips is using the 3D Cursor for precise transformations. For instance, you can snap a vertex to the 3D Cursor in Edit Mode. Select the vertex or vertices you want to snap to the 3D Cursor’s location, right-click, and select Snap Vertices > Selection to Cursor.

On top of that, not only can you use the 3D Cursor to change the origin/pivot point for rotations, but it works the same for scaling too! Give it a shot, and then check out how good your model looks once rendered in Eevee! 

3D Cursor in Animation

The 3D Cursor is invaluable in animation, whether you’re using assets you downloaded or created. You can use the 3D Cursor as a temporary pivot point and animate using that. Once you’re done, snap the object's origin back to its geometry, and you can resume “normal” rotation. You can orbit around the cursor in Blender or even move the cursor along an axis to create complex animations and transformations.

Scripting with the 3D Cursor

If you script using Python in Blender, you might be headed toward advanced techniques. To script with the 3D Cursor, here are the essential methods:

• Get Cursor Position: bpy.context.scene.cursor_location

• Set Cursor Position: bpy.ops.view3d.cursor.set(float1, float2, float3) where the arguments are floats related to the x, y, and z coordinates.

Section 4: Troubleshooting and Tips

Common Issues

One of the biggest issues you can encounter with the 3D Cursor is misplacement. This usually happens because you set its position in the perspective view, which doesn’t allow for precise placement. To ensure it is set correctly, use multiple orthographic views. You can access these quickly using Numpad 1, Numpad 3, and Numpad 7. Misplacing the 3D Cursor is one of the common problems in Blender that can disrupt your workflow, but with a few quick tips, you can easily correct it.

Additionally, it’s a good idea to know how to reset the 3D Cursor to its default location at 0,0,0 quickly. With the 3D Cursor tool selected, press Shift + C. That’s it. This is how you can reset the 3D cursor in Blender to 0 0 0, or set the 3D cursor to the origin in Blender with ease. If you’ve misplaced the cursor, you can easily reset the cursor to origin in Blender or center the cursor in Blender using the same Shift + C command. This also works if you need to reset the 3D cursor position in Blender.

Conclusion

You can be a fantastic Blender user without knowing a single thing about how versatile the 3D Cursor is, but you’re bound to get there a whole lot faster if you do (the right knowledge can speed up your rendering too!). The best way to get the hang of this tool and understand how far its abilities go is simply by practicing a lot with it.
