Adding vertices means creating new points on your 3D model where edges meet
A vertex is a single point in 3D space. When you add vertices to an object in Blender, you are creating new anchor points that let you reshape the model with more control. Think of vertices as corners or joints — the more you have, the more detailed your shape can become. Adding vertices is one of the most common edits you will make when modeling anything from a character's face to a building's walls.
The fastest way to add vertices is the Loop Cut tool, which slices your model with new edge loops and automatically creates vertices all the way around. For single vertices in specific spots, you can use the Subdivide tool or manually extrude and connect edges. Which method you choose depends on whether you need vertices in a line across your model or just in one small area.
Key Takeaways
- Loop Cut (Ctrl+R) creates a line of new vertices all the way around your model, which is the fastest way to add detail to large surfaces.
- Subdivide splits each face into smaller faces with new vertices at the center, useful when you need even spacing across a whole object.
- You must be in Edit Mode (Tab key) before you can add vertices to an existing object.
- Extrude and scale lets you create vertices one at a time by pulling out edges and connecting them, giving you the most control over placement.
Entering Edit Mode and selecting what to edit
Before you add any vertices, you need to switch from Object Mode to Edit Mode. Click on your object in the viewport to select it, then press Tab. The object will turn orange and you will see small dots at each existing vertex. If you see a solid-colored object with no dots, you are still in Object Mode — press Tab again.
Once you are in Edit Mode, you can select which parts of your model to edit. Press A to select all vertices, or use Box Select (B key) to click and drag a rectangle around the vertices you want. You can also hold Alt and click an edge to select an entire loop of vertices at once. The selected vertices turn orange; unselected ones stay black.
Using Loop Cut to add vertices in a line
Loop Cut is the tool you will use most often. Press Ctrl+R and move your mouse over the object. A yellow line will appear showing where the new edge loop will go. Move the line to the spot you want — you can slide it back and forth before you click. Click once to place the loop, then move your mouse again to position it precisely. Click a second time to confirm.
Loop Cut always creates vertices in a complete loop around your model, which means if you cut a cube, the new vertices will run all the way around all four sides. This is useful for adding detail to a large flat surface or preparing a shape for deformation. If you need multiple loops at once, press Ctrl+R and scroll your mouse wheel up or down before clicking — this lets you add 2, 3, or more loops in parallel.
Subdividing faces to add multiple vertices at once
Subdivide splits each selected face into four smaller faces, placing a new vertex at the center of each one. First, select the faces you want to subdivide — press Tab to enter Edit Mode, then press 3 on the numpad to switch to Face Select mode (you will see small dots in the center of each face). Select the faces you want to cut, then right-click and choose Subdivide from the menu.
A panel will appear in the bottom left corner with a "Number Cuts" slider. Increase this number to create more subdivisions — setting it to 2 will split each face into a 3×3 grid, setting it to 3 creates a 4×4 grid, and so on. This method is slower than Loop Cut for adding detail to a specific area, but it is useful when you need even spacing across many faces at once or when you are preparing a low-detail model for sculpting.
Creating vertices by extruding and connecting edges
For precise placement of single vertices, you can extrude an edge and then scale it down to a point. Select an edge by pressing 2 on the numpad to enter Edge Select mode, then click the edge you want to work with. Press E to extrude — the edge will pull away from the model and follow your mouse. Click to place it, then press S to scale it down. Type 0 and press Enter to collapse it to a single point, creating a new vertex at that location.
This method takes longer than Loop Cut but gives you complete control over where vertices appear. It is useful when you need to add detail to a specific corner or when you are building a shape from scratch by connecting individual edges. You can also use the Knife tool (K key) to draw a line across your model and create vertices wherever the line crosses an edge, though this requires more practice to use smoothly.
Merging and removing vertices you do not need
If you add vertices in the wrong spot, you can remove them by selecting them and pressing X, then choosing Delete Vertices from the menu. If you have two vertices very close together that should be one, select both and press M to merge them — Blender will combine them into a single vertex at their average location.
You can also use the Dissolve tool to remove vertices while keeping the shape intact. Select the vertices you want to remove, press X, and choose Dissolve Vertices. This deletes the vertices but connects the surrounding edges directly, which is cleaner than deleting and leaving a hole. Dissolve is useful when you have added too many vertices and want to simplify your model without changing its overall shape.
Checking your vertex count and cleaning up
As you add vertices, your model becomes more detailed but also heavier to work with. You can see how many vertices you have by looking at the top right of the viewport — it shows the total count when you have something selected. For a character face, 5,000 to 20,000 vertices is typical. For a straightforward building, 500 to 2,000 is often enough.
If your model feels slow to edit, you may have added too many vertices. Use the Decimate modifier (in the Modifiers panel) to reduce the count, or manually delete loops you no longer need. You can also use the Remesh modifier to rebuild your model with a cleaner vertex layout, though this changes the shape slightly. The goal is enough vertices to get the shape you want, but not so many that editing becomes sluggish.
Frequently Asked Questions
What is the difference between Loop Cut and Subdivide?
Loop Cut creates a single line of vertices all the way around your model, while Subdivide splits every selected face into smaller faces. Loop Cut is faster for adding detail to one area; Subdivide is better when you need even spacing across many faces at once.
Can I add vertices to a model that is not in Edit Mode?
No. You must press Tab to enter Edit Mode first. If you try to use these tools in Object Mode, nothing will happen. You will know you are in Edit Mode when the object turns orange and you see small dots at each vertex.
How do I undo vertices I just added?
Press Ctrl+Z to undo. You can press it multiple times to step back through your recent changes. If you undo too far, press Ctrl+Shift+Z to redo.
Do I need to add vertices before I can sculpt a model?
Not always. Sculpting tools like Grab and Smooth work on existing vertices, so more vertices give you finer control. But you can also use the Remesh modifier to add vertices automatically before you sculpt, which is faster than adding them manually.
What happens if I add too many vertices?
Your model becomes slower to edit and harder to work with. Blender may lag when you rotate the view or explore modifiers. If this happens, use the Decimate modifier to reduce the vertex count, or delete loops you no longer need.
