Home » SPI SheetMetal Solutions


SPI software for the sheet metal industry is available for the CAD systems Solidworks and Autodesk Inventor. Our solutions expand the functionality of these design applications by providing innovative additional features.

Our Products

Production-ready Unfolding

“SPI creates a flat pattern with the correct bend radii and all corner and flange reliefs, as well as provides a ready-to-manufacture STEP model that perfectly corresponds to the real-life component”, says Production Manager Tilmes.

Your Process Database

Enjoy the benefits of a central administration of your material, tool, and machine data.  Use your own tools in the design and pass them further in the process chain containing all manufacturing information.

Manufacturing Interfaces

A seamless design and production process requires the right software interface. With multiple data export formats available, it has never been easier to transfer all the necessary information to NC programs.

What it does

SheetMetalWorks is a sheet metal design and unfolding add-in for Solidworks that ensures manufacturable results.

The perfect tool for those who design sheet metal parts in Solidworks, SheetMetalWorks streamlines not only the construction but also the manufacturing process.

Main advantages

Even imported parts with inaccuracies are unfolded correctly.

This works also for sharp-edged designs, without relying on the Solidworks sheet metal functionality.

All the technological information stored in the SPI database, such as material and sheet thickness as well as bending, stamping, and forming tools are considered.

What it does

SheetMetal Inventor is an add-in for Autodesk Inventor that significantly expands its sheet metal design and unfolding functionality.

The innovative features of SheetMetal Inventor help to ensure a continuous data flow from design to machine control.

Main advantages

Solids created by lofting as well as curved surfaces, including their bending lines, are easily unfolded.

Unfolding is also possible with free-form surfaces and with bending angles greater than 360°.

Also sharped-edged sheet metal parts designed or imported in Inventor can be unfolded without reworking.

What it does

The SPI CAD Viewer is the ideal tool for viewing GEO and WiCAM XML files.

It can be used as either as a stand-alone tool or as a viewer within the CAD environment. During design, during work preparation, and during distribution.

Main advantages

The display can be configured to show any combination of parameters such as exterior and interior contours, bend lines, bending zones, markers, tool IDs, and machining patterns.

A powerful measuring function allows the measurement of distances, lines, and shapes.


What it does

An online sales channel for sheet metal fabricators and sheet metal service providers

Can be used as an internal calculation tool, as an online customer portal, and as an online shop.

Main advantages

Provide individual quotes just-in-time and thus generate new orders faster and with less effort.

Offer your services around the clock, 356 days a year.

Free up your manufacturing and sales to take care of the essentials: production quality and completely satisfied customers.

Our Customers


We accompany you in your environment, in your IT landscape, within your process chain, and help you to ensure seamless processes from the idea to the finished product.

Andre Tilmes

Production Manager, Kompetenzcenter Abkanttechnik


“The positive impression of the SPI software was reinforced by the ability to unfold all orders. From creating an individual shortening measurement table to the technical support and adjustment of the preset relief cuts, requirements were implemented, adapted, and integrated within a very short time.

None of the competitors could even come close to fulfilling our requirements so completely.”


Tobias Höhnlein

Head of Industrial Engineering, Bader Group

“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.”
