How to Import 3DM File in Revit?

Steps to Import a 3DM File into Revit

Importing a 3DM file into Revit requires a careful approach to ensure the geometry is accurately represented within your project. Below is a structured guide to assist you in achieving this successfully.

Step 1: Prepare Your Revit Environment

Before initiating the import process, open Revit and prepare your workspace. It is advisable to create a new project or family template that suits your design intentions, preferably starting with a generic model type.

Step 2: Access the Import Command

To begin the import process, navigate to the Insert tab located on the Revit ribbon. This tab contains various options related to inserting different file types and elements into your project.

Step 3: Locate the Import CAD Option

Within the Insert tab, identify the Import CAD button in the Import panel. This command provides the means to import external files, including 3DM formats. Click on it to open the import dialog.

Step 4: Select the File Type

In the Import CAD Formats dialog box, you will see a “Files of type” dropdown menu. Click the dropdown arrow and ensure that you select the appropriate format for your 3DM file. Choose the option that corresponds to 3D formats compatible with Revit—this is typically labeled as Rhino (*.3dm) or similar.

Step 5: Navigate to Your 3DM File

Use the file explorer within the dialog to browse to the folder where your 3DM file is saved. After locating the file, select it to prepare for import.

Step 6: Customize Import Settings

Before you finalize the import, Revit may present options related to how the file will be imported (such as positioning and scaling). Review these settings to ensure that they are set according to your project requirements, and make any necessary adjustments.

Step 7: Execute the Import

Once all settings are configured to your preference, proceed by clicking the Open button. Revit will now begin the import process, and depending on the complexity of the 3DM file, this could take a moment.

Step 8: Review the Imported Geometry

After the import process is complete, examine the imported geometry within your project. Ensure that all elements are placed accurately and relevant materials are applied as needed. Make any modifications necessary to align with your design goals.

Step 9: Convert Geometry if Needed

If the imported geometry does not translate directly into Revit elements (like walls or floors), you may need to convert it into native Revit objects. This is usually done by selecting the geometry and using the Create Similar command or similar tools to convert and organize the imported shapes into functional architectural elements.


Frequently Asked Questions

1. Can I import 3DM files from various versions of Rhino?
Yes, Revit is compatible with 3DM files from different versions of Rhino, but it is best to use version 2.0 for optimal performance and compatibility.

2. What should I do if the imported geometry appears distorted?
Check the import settings, particularly the scale and positioning options. Ensure that the original file is not distorted before import, and consider editing the 3DM file in Rhino if necessary.

3. Are there any limitations when importing 3DM files into Revit?
Yes, while Revit can import 3DM files, some advanced features or complex geometries may not translate perfectly. Simplifying the 3D model in Rhino before import can help mitigate potential issues.
