The RPA file extension is associated with the Robot Structural Analysis Professional software, developed by Autodesk as a structural engineering and analysis tool for the AEC industry. The .rpa format is used to save robot projects, including input data (such as computational models and parameters), output data (including numerical and graphical results) and analysis process information. This file type contains all the layout information as well as materials, structural elements and associated properties.
Structure of the File
The .rpa file is created in a proprietary binary format developed for Robot Structural Analysis. It stores project-related data in sections managed by individual source files (.rpo,.rpy,.rpb). Each section includes its own header which contains information such as creation date, project name, project revision. The contents of the individual sections may include any number of text values, numeric values, subsections, and links from one section to another. The format also supports compression.
Similar File Types
This extension is not related to other common file formats such as .rsa, raptor, .rad, or rppx. Those are used by different applications for special tasks.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .RPA) 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 .RPA 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 .RPA 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 .RPA 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 .RPA extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .RPA file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .RPA 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 .RPA file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .RPA file) will be extended to the maximum.
It is also good to check
- if the .RPA file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
