AutoDesk Data Format | Autodesk | Data Files |
The COF file extension is a compressed file format used by AutoDesk, primarily for storing three-dimensional designs and related information. This type of file typically contains 3D models, 2D and 3D drawings, assemblies, parts, animations, simulation models and renderings. The COF files are also known as AutoCAD Core Object Format because they are created by the CAD (Computer-Aided Design) program, AutoCAD. They can be exported to other 3D programs such as VRML, U3D, and STL.
Technical Details
COF files are binary files (not plain text) with a size of up to 500MB. They typically include geometry data in the form of meshes or faces. The faces can also contain material information such as colors and textures. The COF format also includes metadata about the model such as version data and an unique identifier number for each object in the project. Moreover, the COF format is compatible with .DWG, .DXF, and other 3D formats such as .3DS, .STL, and .OBJ.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .COF) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .COF extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .COF file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .COF extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .COF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .COF file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .COF file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .COF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .COF file) will be extended to the maximum.
It is also good to check
- if the .COF file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
