Chief Architect, developed by Chief Architect, Inc., uses .calibz files to package reusable symbols for its design software. These symbols represent graphical elements that can be used in architectural and home-design projects.
After a library is installed, its symbols become available in Chief Architect and can be placed in designs. The format is intended for use with the Windows version of Chief Architect rather than as a general-purpose image or graphics format.
Install Chief Architect on Windows and double-click the .calibz file to install its symbol library. The symbols should then be available in the program's library tools.
If double-clicking does not install the file, open Chief Architect and use its library management or import tools to add the library.
There is no general-purpose conversion utility for .calibz files. They are library packages intended to be installed and used in Chief Architect.
