File with STEP extension contains 3D CAD object data saved in text format that conforms to ISO 10303-21 standard, also know as Standard for The Exchange of Product Data - STEP. The format was developed as a standardized data sharing format for CAD and CAM applications and platforms.
PAR file extension is used by Parchive volume files. PAR file contains marked sequence of bytes generated based on the data archive, which allows data recovery in case of loss or data corruption.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the STEP file after converting to PAR may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from STEP to PAR to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting STEP to PAR does not meet your expectations, you can simply try to find on the Internet a different version of your file in STEP format, properly converted to a PAR file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file STEP the desired result was not achieved, you can try to change the format of STEP file to other than PAR. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your STEP file converted by someone else, and the attempt to convert it to PAR on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the STEP file in its original format (without conversion to PAR file). Such a solution will be difficult to implement, but it certainly will give the best result.
