Union Examples
Combining shapes with union
Union combines overlapping shapes into a single mesh.
Simple Example: L-Shape
- Create two boxes
- Position them in an L configuration
- Make sure they overlap at the corner
- Select both → Union
Result: Single L-shaped object
Practical Uses
Building a Character
- Body (cylinder) + Head (sphere)
- Union creates single mesh
Creating Furniture
- Table legs + table top
- Multiple unions to combine
Organic Shapes
- Overlapping spheres
- Union for smooth-ish combinations
The Process
1. Create Shape A
2. Create Shape B
3. Position with overlap
4. Select A, then Shift+click B
5. Click Union button
6. Single result object created
Important Notes
- Original shapes are hidden (not deleted)
- Result is a new object
- Name your result appropriately
- Internal faces are removed automatically
When NOT to Use Union
- Shapes that don't overlap (no effect)
- When you need to edit parts separately later
- For very complex combinations (can cause issues)
Keep it simple - union 2 shapes at a time!
