3-2-1 ready for production
SPI SheetMetal software extends the sheet metal functionality of the base CAD software with proven features that save time, reduce errors, and optimally link design and fabrication.
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 patterns
100% ready for production. No reworking, no practice parts.
The superior SPI unfolding algorithm considers 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.
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.
The acquisition of the software paid off quickly. We can use the time we save to invest 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.
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.
