Tips to open STP file

Can't open the STP file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open STP files as well as a list of programs that support STP files.

STP file extension

File Name STEP 3D CAD Format
File Category 3D Image Files

The STP file is supported on 7 operating systems. Depending on your operating system, you may need different software to handle the STP files. Below is a summary of the number of programs that support and open the STP file on each system platform.

What is STP file?

A .STP file is a file that contains three-dimensional graphics. It is a text file based on ASCII encoding. The file is saved in STEP (Standard for the Exchange of Product Data). It is supported by most CAD applications. This standard is used as a transmission medium between solutions from different manufacturers. Most of the finished custom designs are just uploaded in this format to allow easy import of the design into your software.

How to open STP file?

The main problem with STEP 3D CAD Format is that the STP file is incorrectly associated with programs. Thus, when you open STP, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the STP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install TurboCAD

The first step is to check if the computer has the TurboCAD program installed. This can be achieved by typing TurboCAD into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file STP.

Programs to open STP file

Remember to download programs supporting STP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of TurboCAD with STP files

If, despite the installed application, the STP file does not start in the TurboCAD application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the TurboCAD application as the default for handling the STP file.

Step 3. Update TurboCAD to the latest version

If, however, after binding TurboCAD with STEP 3D CAD Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the IMSI/Design, LLC. page and install.

Step 4. Check for the following problems with the STP file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to STP files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our STP file. However, remember that not every infected STP file can be recovered, so it is important to take care of regular backups.
Older version of STP file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair STP file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program can also signal the fact of encryption. The encrypted STP files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move STP to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file STP to close. Some anti-virus or backup software may occupy the STP file for a certain period of time. If nothing helps, please reset the device.
