How Do I Open a STP File in AutoCAD?

AutoCAD is a powerful software used for creating and editing 2D and 3D designs. It supports various file formats, including the Standard for the Exchange of Product model data (STEP) files, which have the .stp extension. If you have received a STP file and want to open it in AutoCAD, this tutorial will guide you through the process.

Step 1: Launching AutoCAD

To begin, open AutoCAD on your computer. You can usually find it in the Start menu or on your desktop if you have a shortcut.

Step 2: Creating a New Drawing

To open the STP file, you’ll need to create a new drawing in AutoCAD first. Click on “New” or go to “File” > “New” to create a blank drawing.

Step 3: Importing the STP File

Once you have created a new drawing, it’s time to import the STP file. Go to “Insert” > “Import” or type “IMPORT” in the command line.

Note: If you cannot find the import option, make sure that you have saved your new drawing at least once before trying again.

Step 4: Selecting the STP File

A dialog box will appear asking you to select the file you want to import. Locate and select the STP file from your computer’s directory.

Troubleshooting Tip:

If you cannot see the STP file in the dialog box, make sure that it is not hidden or stored in a different location. You can also try changing the file filter to display all file types.

Step 5: Specifying the Import Options

After selecting the STP file, AutoCAD will present you with import options. These options allow you to customize how the file is imported, such as unit settings and layer assignments.

  • Unit Settings: Choose the appropriate unit settings that match your design requirements. This ensures that the imported geometry is scaled correctly.
  • Layer Assignments: Specify how the layers in the STP file should be mapped to AutoCAD layers. You can either create new layers or assign them to existing ones.

Make sure to review and adjust these import options according to your needs before proceeding.

Step 6: Importing the STP File

Click on “OK” or “Import” to start importing the STP file into your new drawing. AutoCAD will process the file and display its contents on your workspace.

Note: Depending on the complexity of the STP file and your computer’s performance, this process may take some time. Be patient and avoid interrupting it.

Troubleshooting Tip:

If you encounter any issues during or after importing, make sure that your AutoCAD version supports STP files and that it is up-to-date. Additionally, check for any error messages or consult AutoCAD’s documentation for further assistance.


You have successfully opened a STP file in AutoCAD! You can now view, edit, and work with its contents using AutoCAD’s powerful tools and features.

Note: Remember to save your work regularly to avoid data loss and maintain progress.

By following these simple steps, you can easily open STP files in AutoCAD and leverage its capabilities to enhance your design workflow. Enjoy exploring the world of 2D and 3D modeling!
