Free drawing software for Windows, Mac OS X, and Linux
Dia Diagram Editor is free Open Source drawing software for Windows, Mac OS X and Linux. Dia supports more than 30 different diagram types like flowcharts, network diagrams, database models. More than a thousand readymade objects help to draw professional diagrams. Dia can read and write a number of different raster and vector image formats. Software developers and database specialists can use Dia as a CASE tool to generate code skeletons from their drawings. Dia can be scripted and extended using Python.
2D & 3D TeX-Aware Vector Graphics Language
Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. Asymptote provides for figures the same high-quality typesetting that LaTeX does for scientific text.
Synfig is a powerful, industrial-strength vector-based 2D animation software package, designed from the ground-up for producing feature-film quality 2D animation with fewer people and resources.
Domination is a game that is a bit like the well known board game of Risk or RisiKo. It has many game options and includes many maps. Written in java it includes a map editor, a simple map format, multiplayer network play, single player, hotseat, 5 user interfaces and many more features, it works in all OSs that run java 1.4 or higher, and Android.
converts PostScript or PDF files to other vector graphics formats
pstoedit is a tool converting PostScript and PDF files into various other formats suported by different drawing editors. As a prerequesite it needs GhostScript to be installed (binary installation is sufficient).
Vector drawing program for LaTeX using PSTricks
LaTeXDraw is a graphical drawing editor for LaTeX. LaTeXDraw can be used to 1) generate PSTricks code; 2) directly create PDF or PS pictures. LaTeXDraw is developped in Java and thus runs on top of Linux, Windows, and Mac OS X.
K-3D is the free (as in freedom) 3d modeling, animation, and rendering system.
NOTE: FontForge has moved to fontforge.github.io, newer binaries and sources are available at github.com/fontforge. FontForge allows you to edit outline and bitmap fonts. You may create new ones or modify old ones. It is also a format converter and can interconvert between PostScript (ascii & binary Type1, some Type3, some Type0), TrueType, OpenType (Type2), CID, SVG
Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci
TrueType fonts editor. Allows for editing vector-based glyphs
Sodipodi is general vector illustrating application for Linux/Unix and Windows. It uses W3C SVG as native file and in-memory image format and can do many neat things.
Inkscape has now pages support. You can create a multiple page document using Inkscape, just like in Corel Draw. Install this extension, restart Inkscape and you're done. Insert new pages, navigate through pages, print all pages in a single PDF.
This Inkscape extension provides table support for Inkscape. This is one of the features that are present in Corel Draw but are not present in Inkscape. So, just install this extension and you will have table support in Inkscape

JaxoDraw: Feynman Diagrams made easy!
JaxoDraw is a tool to generate Feynman diagrams in a mouse click-and-drag fashion. Graphs can be exported to a variety of graphics formats and arbitrary latex code can be used for labels to produce high-quality publishing-style figures.
Whyteboard is a painting whiteboard application for Linux and Windows, that allows the annotation of PDF and PostScript documents, and image files with common drawing tools.
JHotDraw is a two-dimensional graphics framework for structured drawing editors that is written in Java. It is based on Erich Gamma's JHotDraw, which is copyright 1996, 1997 by IFA Informatik and Erich Gamma.
Various scripts to transform Gimp paths
Interactive designer for Celtic knots
Knotter is a highly configurable interlace designer. Interlace patterns are a kind of design historically used as a decorations in many places and by different cultures, some examples are Celtic knotworks and Islamic interlaces. Knotter aims to allow its user to design such patterns in an intuitive way and to provide easy ways to integrate the result in external general-purpose graphic software. For this purpose, designs created within Knotter can be save in a custom human-readable format and exported as Scalable Vector Graphics and in a wide number of raster image formats.
NoteLab is an advanced "digital notebook" specifically designed for tablet computers. With its stroke smoothing, antialiasing, and "smart rendering," NoteLab provides a beautiful and powerful note taking environment on any operating system.
TouchGraph provides a set of interfaces for graph visualization using force-based layout and focus+context techniques. For now only older code is available, but we are planning to release new versions as well.
Another drawing editor for LaTeX with PSTricks & TikZ
jPicEdt is an extensible internationalized vector-based drawing editor for LaTeX and related packages (TikZ, PsTricks,...), written in Java. It is also a library of reusable high-level graphic primitives.
Sailcut CAD is a sail design and plotting software. It allows you to design and visualise your own sail and compute the accurate development of all panels in flat sheets.
BirdFont is a font editor which lets you create vector graphics and export fonts in TTF, EOT and SVG format. Binary releases are available from the website.
µSprite is a vector graphics editor for ActionScript 3 and haXe written in AS3. It generates AS3/haXe while it is being drawn and parses saved scripts so drawing can continue anytime. It implements multiple layers, masks, tween and path based animation.
