Level-up the sheet metal functionality of SOLIDWORKS

SheetMetalWorks is an add-in for companies that use SOLIDWORKS to design sheet metal for bending.

Simplified design, automated calculations, flawless unfolding of complex parts, easy data transfer to CAM, and much more.

SheetMetalWorks from SPI

Your sheet metal add-in for SOLIDWORKS

  • Connects design and fabrication
  • Cuts down pre-production work
  • Helps to keep track of the costs

Optimal handling of non-native data

Easily fix errors without having to modify the model.

Improved sheet metal design

Specialized commands and exact calculations.

Automatic manufacturability checks

Eliminate the need for costly practice parts.

Manufacturing-ready flat pattern

Containing all the necessary manufacturing information.

Specialized CAM Interfaces

For TRUMPF, WiCAM, Bystronic, LVD, and more.

Easy transfer to CNC programs

e.g., TruTops, PNBend, Stream Bend, CADMAN B.

All common export formats

Includes DXF, GEO, STEP, and WiCAM-XML.

Built-in time and cost calculations

Rule-based estimates at the press of a button.

A streamlined process chain from the idea to the finished product

SheetMetalWorks was launched in 1998. Ever since new features and improvements have been added with every yearly release.

The ongoing compatibility with Solidworks, as well as the integrated and interoperable functionality, has earned SheetMetalWorks the Solidworks Gold Partner status.

Simplified sheet metal design

Reduce errors and save as much as 80% of the design time.

SheetMetalWorks provides automatic corner reliefs, numerous formulas for calculating shortening in the bending zones, optimal handling of multi-body parts, editable material and tool management, and more.

Manufacturing-ready flat pattern

100% ready for fabrication. No reworking, no practice parts.

The superior SPI unfolding algorithm takes into account not only the material and sheet thickness but also your laser, punching, and bending machines. Accurately unfold even freeform surfaces, curved surfaces, and other complex parts.

Easy data transfer to CAM and CNC

Seamlessly connect your design and fabrication.

Manufacturing interfaces and corresponding output formats for a wide range of CAM applications and CNC machines.
Precise, error-free, fast, and cost-effective.

Built-in cost calculation

Calculate the cost of your product in real-time.

Define your rule-sets including everything from material and labor to overhead costs and explore alternatives based on the estimation. Export the results to ERP and production systems.


The acquisition of the software paid off quickly.

Thanks to the good order situation, we can invest the time gained in new projects. An integrated process from the sketch to the detailing to the finished assembly, all in 3D: just a few years ago it was a dream of the future. Now it is standard in the design department at Contour.

Jonas Simmes, Production Engineer, Contour Covering Technology | the Netherlands

We have brought strong and dynamic partners on board.

We have optimized our processes and can continue to meet the increasing demands of our customers. In SPI we have found a development partner who understands our processes and turns their expertise into powerful software solutions.

Tobias Höhnlein, Head of Industrial Engineering, Bader Holding | Germany

It’s process-orientated, consistent, and, above all, error-free

Thanks to the integration of the SPI add-ins for the output formats we can transfer the data from design directly to production. A big step forward and a real gain in terms of automation and consistency of our processes.

Several thousand users worldwide rely on SPI SheetMetalWorks to digitize their sheet metal process chain.

Do I need SOLIDWORKS to use the software?

Yes. SheetMetalWorks requires the corresponding version of registered SOLIDWORKS software, e.g., SOLIDWORKS 2021 for SheetMetalWorks 2021.

Can I receive a training to help me to get started?

But of course! When you purchase our software, we offer you an online or in-person training that is custom-tailored to your needs. We will show you how to make the most out of SheetMetalWorks in your sheet metal process chain.

Is software support available?

Our support customers enjoy email and phone support in English and German, as well as remote maintenance via TeamViewer.

Is custom software development possible?

We at SPI are CAD software experts with 40 years of market experience. Contact us to discuss how we can incorporate your special requirements to ensure that the software optimally supports your processes.
