The .idw file stands for the Autodesk Inventor designs. Designers can design their projects using the software and save it in a .idw file for sharing. The file type provides mobility and can be accessed on any machine that has Autodesk Inventor Software. It can be also opened in a read-only mode using Autodesk Inventor View.
The file structure allows the designers to save their complete work or save it in the Part files. This file is often used in the testing and analysis during the simulation phase of the project. The file is designed based on the architecture that many other Autodesk software have and thus provides interoperability between different platforms.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .IDW file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .IDW file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .IDW file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
