With IRONCAD's Sheet Metal features, you can create folded sheets in 3D and unfold them into a flat version. You can dimension both the folded and unfolded version of a 2D drawing and also export the unfolded version to DXF at the touch of a button for use in the laser cutter. Sheet Metal for 3D CAD has never been faster and easier!

IRONCAD has many different methods and tools for Sheet Metal and sheet bending. As a user, you can choose between different methods to create bends. You can work with 2D- planes and extrude sheet metal in 3D from a 2D cross-section if you wish. And you can even draw lines on a sheet to show where you want the bend. Of course, you can choose the angle, bending radius, etc. per line. The lines can be adjusted by dragging handles in the 3D environment!
IRONCAD offers a comprehensive package of Sheet Metal capabilities. You can create anything from simple sheet metal bending to more advanced, such as lofted sheet metal (e.g. "round to square") by press bending. You can set how many bends you want to use to achieve the desired shape. How many degrees each individual bend should be bent is automatically shown on the 2D drawing. Of course, with a few quick clicks, you can export an unfolded plate to 2D DXF format for use in the laser cutting machine.
IRONCAD Sheet Metal functions allow you to easily manage 3D models even from other CAD systems. For example, import a part in STEP format, modify it directly if necessary, see the example of changing the hole diameter without having history. Or convert it to a SheetMetal part in IRONCAD and get access to more special tools and build on it, then unfold it.
The Sheet Metal catalogue is always easily accessible on the side of the screen in IRONCAD. You can instantly drag and drop different shapes on your 3D model. Many of the shapes are adapted for deformation via punching tools or cutting/laser cutting. You can customize dimensions freely or choose from the desired size in table.
Based on the Sheet Metal functions in IRONCAD you can also design corrugated cardboard packaging. Import the items to be shipped in 3D. Drag-and-drop different types of boxes and fittings from the side of the screen into the 3D environment. Drag handles directly on the 3D model to adjust the dimensions of the box and fittings. Create cut-outs to hold goods in place automatically. Unfold the interior and box with one click. The unfolded version shows where to cut and fold the corrugated cardboard. Quickly and easily export to 2D DWG/DXF format for use in production.


With over 50 years of experience in sheet metal processing, welding in aluminum, laser cutting and punching in sheet metal, Länna Svets has conducted its business in Merlänna outside Strängnäs. Länna Svets & Mekaniska uses IRONCAD for product development and sheet metal bending. IRONCAD can handle imported assemblies in the same file and modify sheets and other shapes directly. Among other things, when it comes to importing and exporting different CAD formats, IRONCAD is really good but also to create new ones.
