SolidWorks sheet metal design becomes much easier when the model reflects how the part will actually be fabricated. A production-ready model should support both the formed geometry and an accurate flat pattern.
Start with the manufacturing process
Before creating the model, identify material thickness, bending method, tooling limits and the likely cutting process. These inputs affect bend radius, reliefs and flange dimensions.
Important SolidWorks sheet metal features
- Base Flange/Tab
- Edge Flange
- Sketched Bend
- Jog
- Hem
- Corner Trim
- Bend Relief
- Flatten
Use a realistic bend setup
Set material thickness, bend radius and bend allowance or K-factor according to your production process. If the shop uses a validated bend table, use that data rather than relying only on generic defaults.
Check the flat pattern
Inspect the flat pattern for minimum flange lengths, bend relief, hole locations and collisions. Export the correct DXF configuration when the part will be laser cut or punched.
Common mistakes
- Using an unrealistic bend radius.
- Ignoring tool access.
- Placing holes too close to bend lines.
- Failing to validate the K-factor.
- Sending the formed model without checking the flat pattern.
Production workflow
A good workflow is: define material → model the formed part → apply manufacturing features → flatten → review DXF → fabricate a sample → compare dimensions → update the sheet metal parameters.
Strong SolidWorks sheet metal design skills connect CAD modeling directly to fabrication and production engineering.
