The file type can sometimes tell you which program might open the file. If you have CIM files, they are most likely types of Uncommon Files. A program that works with Uncommon Files should open CIM files.
While we do not yet have a description of the CIM file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below.
The initial CGM implementation was effectively a streamed representation of a sequence of Graphical Kernel System (GKS) primitive operations. It has been adopted to some extent in the areas of technical illustration and professional design, but has largely been superseded by formats such as SVG and DXF.
The World Wide Web Consortium has developed WebCGM, a profile of CGM intended for the use of CGM on the Web.
A CGM file is an image saved in a vector graphics format designed to support the needs of many graphics applications. It was originally used for clip art libraries, but newer revisions (based on the ISO/IEC 8632 standard) are now commonly used for CAD drawings.
CGM was developed by W3C in 1999. As a metafile, i.e., a file containing information that describes or specifies another file, the CGM format has numerous elements to provide functions and to represent entities, so that a wide range of graphical information and geometric primitives can be accommodated.
All graphical elements can be specified in a textual source file that can be compiled into a binary file or one of two text representations. CGM provides a means of graphics data interchange for computer representation of 2D graphical information independent from any particular application, system, platform, or device.
