Raster Files
It’s important to know your file extensions, formats and the quality they produce when requesting formal patent drawings. Different file formats not only affect the visual quality but also the ease with which they can be modified or used. Let’s review the three main types of files – 3D, Vector, and Raster – and understand their impact on your patent illustrations.
For a complete overview of extensions, formats and the quality, refer to the File Formats & Quality infographic at the bottom of the page for various file extensions.
3D Files
3D files are often considered the gold standard in patent drawing quality. They offer a comprehensive view, allowing drafters to visualize every angle and detail of an invention. Take, for instance, the 3D representation of an apple. You can discern intricate details, including the relationship between the stem and leaf. Such clarity is crucial in patent drawings, where every detail can be critical. Common software and their extensions for creating 3D files includes:

.obj
.3dm
Rhino 3D model
.eprt .easm .edrw
eDrawings
.stp .step
STEP (Standard for Exchange of Product Data)
.dwg*
AutoCAD Drawing File
*also for 2D vector drawings
.sldasm
Assembly
.stl
Stereolithography
.sldprt
SolidWorks Part
Vector Files
While not as detailed as 3D files, vector files are renowned for their crisp and clear lines. These files are important when you need to enlarge drawings without losing quality. Consider the vector image of an apple; its lines remain sharp and defined even when zoomed in or manipulated.
* It’s important to note that not all PDF files are vector-based, but all vector files can be converted into PDF format.
Common software and their extensions for creating Vector files includes:


Adobe Acrobat
.svg
Scalable Vector Graphics
.dwg*
AutoCAD Drawing File
*can also contain 3D data
.dxf*
AutoCAD Interchange File
*has limited 3D capabilites
.eps
Encapsulated PostScript
.ai
Adobe Illustrator
.cdr
CorelDRAW
Raster Files
Raster files are widely used, but they come with limitations, particularly in terms of scalability and clarity. When resized, these images can pixelate and become fuzzy, leading to a loss of detail. Look at the raster apple image. The stem and leaf of the apple to the right are now blurred to create a shape different from the 3D apple. We can no longer tell what section is a leaf and what is a stem.
Common software and their extensions for creating Raster files includes:


.jpeg
Compressed Photo
.png
Portable Network Graphics
.gif
Graphics Interchange
.webp
WebP
.bmp
Bitmap
.tiff
Tagged Image File Format
.psd
Adobe Photoshop

for Patent Drawings
MATTERS
The caliber of the image you provide for your patent drawings can significantly impact the entire process. Opting for high-quality images streamlines the process and accurately captures the essence of your invention.
