What is SLDPRT file?

SLDPRT file contains 3D drawing of an element that is a part of larger project of a device or construction. Such project is stored in a proprietary binary format native to SolidWorks software. The software allow users to design assembly models and save them as SLDASM files, technical drawings, or simulations and animations. Each new SolidWorks CAD version offers new features and additonal functions, so SLDPRT projects created using later versions may not be fully if at all backward-compatible. SolidWorks uses the following format to save project data:

  • SLDPRT – project part file,
  • SLDASM – assembly file that can be composed of many SLDPRT files,
  • SLDDRW – SolidWorks drawing file.

Each above-mentiond format is a container file that stores various project files, including images (preview image), as well as metadata. SLDPRT can be viewed using dedicated project viewer tools. Many CAD applications allow users to import SLDPRT data and convert it to its native format. However, such conversion is not always possible without some data loss.

SolidWorks projects integrate very well with other types of CAM (Computer Aided Manufacturing) software tools. SLDPRT files are also a good data echange format as they allow users to share relevant parts of their projects without the need to disclose whole project stored in SLDASM files. SolidWorks has been on the market since 1995 and competes head-to-head with other CAD tools. New versions are released each year, available as standard, professional, premium, education, or simulation packages.

  • Select Choose another app → More apps
  • To finalize the process, select Look for another app on this PC entry and using the file explorer select the SolidWorks installation folder. Confirm by checking Always use this app to open SLDPRT files box and clicking OK button.

Change the default application in Mac OS

  • By clicking right mouse button on the selected SLDPRT file open the file menu and choose Information
  • Open the Open with section by clicking its name
  • From the list choose the appropriate program and confirm by clicking Change for all....
  • If you followed the previous steps a message should appear: This change will be applied to all files with SLDPRT extension. Next, click the Continue button to finalize the process.

Step 4. Ensure that the SLDPRT file is complete and free of errors

Should the problem still occur after following steps 1-3, check if the SLDPRT file is valid. Problems with opening the file may arise due to various reasons.

Should it happed that the SLDPRT is infected with a virus, this may be that cause that prevents you from accessing it. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the scanner detected that the SLDPRT file is unsafe, proceed as instructed by the antivirus program to neutralize the threat.

2. Verify that the SLDPRT file’s structure is intact

If you obtained the problematic SLDPRT file from a third party, ask them to supply you with another copy. The file might have been copied erroneously and the data lost integrity, which precludes from accessing the file. It could happen the the download process of file with SLDPRT extension was interrupted and the file data is defective. Download the file again from the same source.

Sometimes in order to access files user need to have administrative privileges. Switch to an account that has required privileges and try opening the SolidWorks Part Format file again.

4. Check whether your system can handle SolidWorks

If the system is under havy load, it may not be able to handle the program that you use to open files with SLDPRT extension. In this case close the other applications.

5. Ensure that you have the latest drivers and system updates and patches installed

Regularly updated system, drivers, and programs keep your computer secure. This may also prevent problems with SolidWorks Part Format files. It may be the case that the SLDPRT files work properly with updated software that addresses some system bugs.
