STP is a format which is used for the storage of 2D and 3D images data. It is especially useful for CAD software. In order to view such images, the Free STP Viewer is an ideal choice. This is a tool that comes with a host of features and is ideal for all those who deal with CAD on a daily basis. However, it is very simple and can be managed even by someone who is new to such technology. There is a 'help' file in case of any glitches and the fact that it comes with a user friendly interface is yet another advantage. All of the functions are available on the main menu itself, making it an effortless app. The software is absolutely free of cost. There are no hidden charges or trial versions of the same. Once it is downloaded onto a system that runs on Windows OS, it can be used easily without any additional specifications. Since 3D images require a lot of navigation, the Free STP Viewer ensures that this is made effective. Users can opt for the shading effects as well in order to analyze the data much better. The response time of the tool is also noteworthy. Since it is a small sized file, it does not require much disk space either. Another benefit is that there is no malware or virus that can affect the device. It is a clean app that downloads in a jiffy and works on low to moderate system resources. There are very few such apps which are as useful as the Free STP Viewer. Be it any kind of design, model or data, there is no loss when this viewer is used. It is highly recommended to be downloaded for all those working in industries.
