LibreCAD: 2D Computer aided design

LibreCAD is a fully comprehensive 2D CAD application that you can download and install for free. There is a large base of satisfied LibreCAD users worldwide, and it is available in more than 20 languages and for all major operating systems, including Microsoft Windows, Mac OS X and Linux.

GeoFryPlots: Fry point-to-point strain analysis plots

GeoFryPlots performs strain analyses using the Fry point-to-point method. Data can be either read in from an ascii file (as pairs of x,y coordinates) or can be digitised directly into a data window using the mouse. Bitmap images to be digitised can be loaded into the data window from file. Fry plots are displayed in a separate FryPlot window within which a best-fit strain ellipse to the plot can be constructed using the mouse.

Strain Calculator: Strain and shear zone calculations, including general plane strain shear

Strain Calculator presents strain data and calculations graphically and numerically. Conversions of strain ratios to stretches at a given volume change can be plotted directly onto a logarithmic strain plot. Shear zone parameters (ellipticity, deformed and undeformed orientations, etc.) for any shear strain value or general shear vorticity

Blender: 3D creation for everyone, free to use for any purpose.

Free Software, great community, and 100% open. Blender is being made by hundreds of people from around the world; by studios and individual artists, professionals and hobbyists, scientists, students, VFX experts, animators, game artists, modders, and the list goes on.

All of them are united by the desire to have access to a fully free/open source 3D creation pipeline.
Volunteers are welcome to work on parts of the software, on the websites, documentation, education, design proposals, testing, and many more topics.
