XTrackCAD is a CAD program for designing model railroad layouts. You can easily create layout of any scale or size. Libraries for many brands of track and turnouts are included. Adding new components is easy with the built-in editor.
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.
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).
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
K-3D is the free (as in freedom) 3d modeling, animation, and rendering system.
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.
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
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.
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.
A graphical Finite State Machine (FSM) designer.
A graphical tool for designing finite state machines and exporting them to Hardware Description Languages, such as VHDL, AHDL, Verilog, or Ragel/SMC files for C, C++, Objective-C, Java, Python, PHP, Perl, Lua code generation.
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.
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.
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.
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.
Various scripts to transform Gimp paths
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.
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.
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.
Automata editor is a vector editor for drawing finite automata according to VauCanSon-G format with tools for working with finite automata such as basic algorithms, exporting transition table to LaTeX format and automata work simulation.
