Why would I use a DXF file for quoting?

Xometry's Sheet Cutting Services utilize laser cutting and waterjet cutting to produce affordable flat parts with custom outlines. We accept various file types from STP, SLDPRT, IPT, PRT, SAT, and DXF. DXF files are uniquely suited for sheet cutting because they are two-dimensional, top-down representations of the final part. DXF stands for Drawing Interchange Format or Drawing Exchange Format.

DXF files are exported from CAD software and even many art and design programs. DXF files are vectored, meaning that a mathematical formula versus pixels defines the lines. Unlike raster images such as photos, vectored DXF files will not lose any resolution regardless of how far you zoom in on the image.

DXF Requirements

Cut files only

The best way to get an instant quote with a DXF is to upload a cut file and not the full drawing. Using a DXF will create a quote for a “flat cut” sheet part without bends. If there are bends in the part, the best way to quote is by using a 3D CAD model formed to the final shape.

Annotations are okay!

Because annotations (like bubble annotations or tolerances) are not part of the geometry, we are able to filter those out. However, tolerance callouts will need to be specified in the instant quote and included in an attached drawing for accurate pricing.

Does not contain title blocks

Extra-drawn features can be confused with cut geometry and will cause the file processing to fail. Multiple layers will be merged into a single layer as part of the geometry process.

Segments should not be grouped into BLOCK entities

Files cannot contain line segments or curved features in a BLOCK section.

All 2D geometry must be in the XY-plane

All drawing features must be oriented in the XY plane. Make sure the file is a 2D (not 3D) DXF file.

No inserts or assembled components

Files cannot contain inserts or multiple assembled components.

Wireframes should be visible

Files should have a sketch visible and especially the boundary sketch.
