How to open file with .STP extension?

Don’t you know what program to use to convert the .STP file? Do you want to convert a .STP file into a different format? Below you will find helpful information.

File extension .STP

Full Name Developer Category
ISO-10303 STEP Product Data Format N/A 3D Image Files
.STP

The STP (STEP 3D CAD File) is a file extension typically used in three-dimensional computer aided design (CAD) programs related to 3D. The STP, or Standard for the Exchange of Product Model Data, was first introduced by ISO 10303-21 and provides users with the ability to share 3D objects. In addition to the STP (STEP 3D CAD File), the same ISO 10303-21 standard also includes file extensions such as .IGS,.IAM, and.XLTRT.

Features of STP File Format

The STP file format is particularly popular in the engineering sector because it's robust. It can easily store all of the necessary geometric elements which describe a product. This also include textures, edges, colors and more. The usage of this format is not limited as the developers can even use it for storing mechanical CAD data. As it is designed to store CAD data, users can expect important features such as parametric modeling, feature-based CAD or synchronous technology.

Supported File Formats

Though an official program is yet to be available, Microsoft Windows support user-developed programs like VariCAD Viewer ( VariCAD) or Open CASCADE Technology Viewer ( Open CASCADE Technology) which can open STP (STEP 3D CAD File) files. Moreover, Apple's Mac OS X received general CAD support with Autodesk's Inventor with special focus on step file formats like .STP, .IGES, and .ASE. The platforms such as UNIX, Linux and mobile have also been improved over time and made compatible to read data from STP files. Furthermore, there are web-based services which may assist users in displaying/viewing.stp files on their browser.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .STP) 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 .STP 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 .STP 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 .STP 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 .STP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .STP file. Sometimes you have to repeat the operation several times.

Other instructions

If none of the programs listed by us to work with the .STP 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 .STP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .STP file) will be extended to the maximum.

It is also good to check

  • if the .STP file has no errors
  • or if it has been copied (or downloaded by the browser) thoroughly
In such a case it is best to try to download the .STP file again from the same source on the Internet (or look for another source). If you received the file from another person, ask this person to re-send it. However, if the file was copied from some media, repeat the copying operation.
