How to Open an STP File in AutoCAD

Importing or “opening” STP files in AutoCAD is a straightforward process that can be accomplished in a few steps. You’ll be able to use one of two methods to open STP files.

NOTE: You should be in the 3D Modeling Workspace to import an STP file. 

Method 1: Using the Quick Access Toolbar

You need to follow a 3-step process to open an STP file in AutoCAD using the tabs in the Quick Access Toolbar: 

Step 1: Select the “Insert” Tab function

Step 2: Locate the “Import” panel and click the “Import” button

Step 3: Find the STP file you want to import in the file explorer and click “Open”

Method 2: Using the Command Line Interface

Using the command-line interface in AutoCAD can be faster than using the Quick Access Toolbar:

Step 1: Open the command bar (Ctrl+9 on Windows; Cmd+3 on Mac)

Step 2: Type “IMPORT” in the command bar and hit the Enter (or Return) key

Step 3: Find the STP file you want to import in the file explorer and “Open”

What Happens Once You Click “Open” and Start Importing the STEP File Into AutoCAD

A window may pop up showing that the import process has started. You can safely close the pop-up and let the import carry out in the background. You will receive a notification message indicating that the import is complete (see above).

NOTE: You may have to insert the file manually once the file is complete to make it appear on-screen and use it for your 3D model. You can do this by clicking the file name or on the notification icon.

Common Issues Users Face Trying to Open an STP File in AutoCAD

Some common issues you may encounter when trying to open an STP file in AutoCAD are as follows:

• Computer lacks resources to open the file
• Corrupt file
• Repair File
• Translation errors in 3D image data
• Improperly installed host application
• Fix host application errors
• AutoCAD LT does not include STP import functionality

Importing or “Opening” an STP File in AutoCAD

The Standard for the Exchange of Product Data file, or STEP (STP), is a popular 3D object file type.

Though AutoCAD opens STEP (STP) files, it does not natively support the STEP file format. It does not read or write STP files natively; instead, converting files using a built-in translation tool. 

Lossless, Error-Free 3D Model File Imports

Users can experience translation errors, loss of metadata, and version control issues when importing or exporting non-native file formats. To streamline workflows, consider using a dedicated file converter like Spatial’s 3D InterOp. It allows:

• Native data translation for a wide range of 3D object file types
• Interoperability with popular CAD software
• Selective data imports
• Stable CAD topological identifiers
• And more
