Drawing Guidelines

To ensure the fastest, most accurate parts, please make sure your files meet our guidelines. The better the file, the better the parts! We work with 2D and 3D files in formats we accept. These files need to be in 1:1 scale.
2D files must be in .dxf, .dwg, .ai, or .eps vector format. There should only be one part per file, and only the cut lines for the part you wish us to produce. 3D files must be in .step or .stp format.
Bent parts will need lines indicating the center of each bend. Please see our bending guidelines for more information.

Upload a 3D file for modeled parts

If you design a part in a 3D CAD program like Fusion 360 and then export a 2D vector file, sometimes 3D entities can be left over during the export process and cause an error.

Solution

Save your 3D design in the STEP or STP format if possible.

Make sure your parts meet our 3D File Guidelines before uploading your STEP/STP file to our website.

If you can’t save a STEP/STP file, see our export tutorials for guidance on getting a flat pattern that meets our 2D file guidelines.

Avoid open entities

Sometimes entities (also known as “cut paths”) are left open during the design process, or there are unintended results due to a file conversion.

We need all cut paths closed to avoid issues while producing your parts.

Solution

Ensure all cut paths in your design form closed shapes.

See our CAD tutorials and guidelines for help preparing your design files for production.

Typically, your part preview won’t fill in gray if open cut paths are present.

Open Entities

Ensure your file is valid

If you convert your design file from one format to another, it may not result in a usable file.

Sometimes errors can happen when exporting or saving a file directly from CAD programs as well.

Solution

Avoid file converters if possible.

We recommend designing in a recommended software program and exporting a file format we accept (.step, .stp, .dxf, .dwg, .eps, or .ai) directly from there.

Take a look at our export tutorials for help getting a cut-ready file from popular design programs.

Meet our nested file requirements

When multiple parts are nested into a single file, there can be issues if the file does not meet our guidelines.

Specifically, parts should not share cut paths, have overlapping cut paths, or include parts within parts.

Solution

Ensure files containing multiple parts meet our Nesting Guidelines.

Please note, we only accept pre-nested parts for 2D vector format files (.dxf, .dwg, .eps, or .ai).

STEP/STP format files must only have one part per file; we’re unable to process assemblies. See our 3D File Guidelines for more information.

Upload a file format we accept

If you upload a part file in a format we don’t process, it won’t be possible to get a quote.

For 2D vector files, we only accept .dxf, .dwg, .eps, or .ai (Adobe Illustrator) format files.

For 3D files, we only accept .step or .stp format files.

Solution

Take a look at our export tutorials for help getting a cut-ready file in one of the formats we accept!

Please note, we can’t accept mesh files and do not provide any 3D machining services at this time.

If you have an image file (.jpeg, .png, .pdf, etc.) we have tutorials to help you convert your art to a vector format in Adobe Illustrator and Inkscape!
