How do I set up my part for bending?

1. Upload a file format we accept

To set up part files for bending, plan to upload a file format we accept.

Currently we accept STEP and STP format 3D files, and DXF, DWG, EPS, or AI format 2D vector files. The 2D file should only show your part’s cut geometry and bend location lines. We do not require a 3D file for bending, although you are encouraged to attach an image preview to your order to help us understand your project.

If you design your parts in non-CAD software (Adobe Illustrator), please send us the original (native) .ai file. We’ll take care of the conversion on our end. While we accept .AI and .EPS files, it’s critical that your bend lines are parallel when uploaded from these software or the file will delay our process.

For the fastest turnaround on your order, we recommend setting up your parts for bending in a CAD software.

2. For 2D files, use the correct bend line type

Reference this chart to know what kind of lines are needed to indicate the bends in your part. Each bend line should mark the center of each bend. The bend line type changes based on what software you use:

SoftwareFormatBend line
Adobe Illustrator.aiSolid, separate color from cut lines
AutoCAD.dxfDashed line (not hidden)
CorelDraw.epsSolid, separate color from cut lines
Fusion360.dxfSolid line (default)*
Inkscape.epsSolid, separate color from cut lines
SolidWorks.dxfDashed line (not hidden)

*For Fusion360 you will need to apply a thickness, convert to sheet metal, create a flat pattern, export .dxf, then convert spline to a polyline. This will result in 3 solid lines to export. The center is automatically detected in the SendCutSend app for bending. See How To Export to DXF in Fusion 360 for more information.

3. Check your design with our bending calculator

Use our bending calculator to ensure that your formed parts will have the desired final dimensions. Set up your design with our specifications for the material you choose. In programs like Fusion 360, this means your part will need to be set up using sheet metal rules that use our K factor and bend radius specifications.

Please note: we do not bend parts with custom radiuses. Find the bend radius for each material thickness on our bending calculator page or in the Material Details for the chosen material.

4. Don’t use notes; simply configure parts in our app!

Do not leave notes in your file indicating the bend angle. During the ordering process, you will be able to specify the bend angle when you add the bending service to your parts. Learn more about why we don’t require callouts or notes!

If your part file is set up for bending, you should be able to configure each bend line in SendCutSend's app.

Whether you upload a 2D or 3D format file, you will be able to view your bends in a 3D model during the checkout process to make sure the angles and flange orientations are correct.

Setting up part design files for bending can be a complicated process, so review all of our bending guidelines to make sure your parts fit within our requirements for bending!
