C.a.R. stands for 'compass and ruler'; and it is an open source geometry application. This program features a context-sensitive multilingual GUI with a nice layout and tons of tools, which can help us to work with geometrical constructions, including animated and three-dimensional one. We can draw/edit lines, points, circles, perpendicular lines, parallel lines, midpoints, functions, curves, angles, macros, breakpoints, set assignments, add text, use the color palette and grid, paint with our mouse, set macroparameter and definitions, set the object color and thickness, replay the constructions, choose the beginner mode, export to HTML, export templates, and much more. The sample section allows us to load and work with already made applications, templates, autodemos, macros, etc. This comprehensive program may help students, teachers, designers, engineers, and so on. A discussion forum offers information and support. It is possible to contribute to the further development of this free utility, report bugs, translate to other languages, etc. This program needs Java to run, and it supports all platforms.
v8.77 [Sep 1, 2008]
Moved C.a.R. to Sourceforge.
Conditional formatting for polygons.
Greek translation by Giorgos Vasilopoulos.
Ticks on segments and angles.
Invisible macro objects no longer used as job targets.
Export dialog now remembers switching off icon for macro definition.
More than one applet on one HTML page (not recommended!) works more stable now.
Unlimited colors are now possible. Enable the button for this in the icon bar, if you want to set an own default color.
Fixed zeros sets with functions which are invalid at some points.
Error from 8.82 with exp function.
Error in macro execution, when the target was a bound point, and an intersection was created.
Expressions with numbers in exponential format.
Expressions, which are macro targets, are now visible.
User functions in macros, which depend on other objects, now work as expected.
