How to Thicken Surface in SolidWorks: Step-by-Step Guide
In SolidWorks, you can thicken a surface by selecting the
Thicken feature from the Features toolbar, then choosing the surface and specifying the thickness value and direction. This converts the surface into a solid body with the desired thickness.Syntax
The Thicken feature in SolidWorks requires selecting a surface or face, then setting the thickness value and direction.
- Surface/Face: The surface you want to thicken.
- Thickness: The distance to add to the surface to create solid volume.
- Direction: Choose one side, both sides, or reverse side for thickness.

Thicken(Surface, Thickness, Direction)
Example
This example shows how to thicken a flat surface by 5 mm in one direction.
plaintext
1. Open your SolidWorks part with a surface.<br>2. Go to Features tab and click <code>Thicken</code>.<br>3. Select the surface to thicken.<br>4. Enter <code>5 mm</code> for thickness.<br>5. Choose <code>One Direction</code>.<br>6. Click <code>OK</code> to create a solid body with thickness.
Output
The surface becomes a solid body 5 mm thick in the chosen direction.
Common Pitfalls
- Not selecting a valid surface or face will disable the Thicken option.
- Entering zero or negative thickness will cause errors.
- Choosing the wrong direction can thicken inside the model, causing geometry conflicts.
- Trying to thicken a closed solid body instead of a surface will not work.
plaintext
Wrong: Select a solid body and try to thicken (feature disabled).<br>Right: Select a surface or face only before applying Thicken.Quick Reference
Use this cheat sheet when thickening surfaces in SolidWorks:
| Step | Action | Notes |
|---|---|---|
| 1 | Select surface or face | Must be a surface, not a solid body |
| 2 | Click Thicken feature | Found in Features toolbar |
| 3 | Set thickness value | Positive number in mm or inches |
| 4 | Choose direction | One side, both sides, or reverse |
| 5 | Confirm with OK | Creates solid body from surface |
Key Takeaways
Always select a surface or face before using the Thicken feature.
Specify a positive thickness value and correct direction to avoid errors.
Thicken converts surfaces into solid bodies by adding volume.
Check geometry after thickening to ensure no conflicts or overlaps.
