Precision Alignment: Building a Bridge with 3D Cursor

We must make Blender recognize that special point you want to go to the world origin:

• Step 1: Go to Edit Mode (Tab).
• Step 2: Select the single point (Vertex) you want to be exactly at 0,0,0.
• Step 3: Press Shift + S and select **Cursor to Selected** from the pie menu.
• Result: The red-white 3D Cursor is now sitting exactly on that point.

Blender moves objects according to their "center points" (that small orange dot). We must move this center to our selected point:

• Step 1: Return to Object Mode (Tab).
• Step 2: Right-click while your object is selected.
• Step 3: Select **Set Origin** -> **Origin to 3D Cursor**.
• Result: The object's orange center point has moved onto your selected special point.

Now that your object's center is the point you want, you can reset it to the world origin in seconds:

• Shortcut: Press Alt + G while the object is selected.
• Alternative: Manually set **Location X, Y, Z** values to 0 in the N-Panel on the right (N key).
• Final Result: Congratulations! That point you selected is now sitting exactly at the 0,0,0 coordinates.

Especially when importing models to Roblox or making rotating parts like a door hinge:

• Error-Free Placement: Ensures your models sit at the exact coordinates you want when imported into Roblox Studio.
• Pivot Point: When you rotate the object (R), it will now rotate around that selected point.
• Modular Working: It is the most professional way to prevent millimeter gaps when joining parts.
