[Video](https://hexagondownloads.blob.core.windows.net/public/Leica/RC%20DOCS%20videos/Steel%20extraction%20Revit.mp4) Workflow video for steel extraction in CloudWorx for Revit ## Practice Data [Plant dataset.lgsx](https://hexagondownloads.blob.core.windows.net/public/Leica/Sample%20Data/Steel_modeling_revit.lgsx) ## Initial Procedures ### Importing Project Data 1. In the **Project** panel, click **Open LGSx**. ![Open LGSx.jpg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Open%20LGSx.jpg) 2. Click **OK** to clear the notification regarding the units. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(55).jpg) 3. Browse for the necessary dataset and сlick **OK** to import it into CloudWorx.![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(56).jpg) 4. Remove the scope boxes since they are not required for this workflow. Simply click any edge of a box and press **Delete**. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(57).jpg) ### Adjusting Level Extents 1. In Revit’s Project Browser, navigate to **Elevations** and select the desired elevation view. In this case, it’s **East**. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(58).jpg) 2. Click and drag the view area boundary to expose the entire point cloud. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(59).jpg) 3. Drag Level 1 so that it aligns with the ground level of the steel at the concrete footings. ![Basic Steel Modeling workflow - Step 16.png](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Basic%20Steel%20Modeling%20workflow%20-%20Step%2016.png) 4. Drag Level 2 to the top of the Level 2 columns. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(60).jpg) 5. As a result, the levels should be adjusted as shown below. ![https://ajeuwbhvhr.cloudimg.io/https://colony-recorder.s3.amazonaws.com/files/2025-11-20/9ebb732a-df59-45c9-9add-810ddbedc73e/screenshot.webp?tl_px=0,0&br_px=2104,1150&force_format=jpeg&q=100&width=1120.0](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/screenshot(1).webp) 6. Switch to the 3D view. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(61).jpg) ## Steel Extraction ### Steel Objects Classification 1. Use the classification feature to identify steel shapes in the point cloud and streamline steel modelling. Go to **Rendering** | **Color Mapping.** ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(62).jpg) 2. In the **Point Cloud Color Mapping** dialog, select **Classification** from the **Global Mapping** drop-down list and click **Apply**. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(63).jpg) 3. The **Class Visibility** button should become active. Click it, and the **Point Cloud Classification** dialog will open. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(64).jpg) 4. Turn off all layers. > [!TIP] > **Tip:** While holding the **Shift** key, select the first and last layers, and then click any check box to deselect all. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(65).jpg) 5. Scroll through the class list to Index 130, labelled Steel structure column, and select the check box next to it. Close the **Point Cloud Classifications** dialog. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(66).jpg) 6. Close the **Point Cloud Color Mapping** dialog. Now, only steel column objects are displayed. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Basic Steel Modeling workflow - Step 28.jpg) ### Fitting Steel Objects 1. Navigate to **Fitters** | **Steel**. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(67).jpg) 2. In the **Fit Steel** dialog: 1. Select the **Use Steel Catalog** check box and then select the necessary steel catalog. For this workflow, it is **Europe**. 2. Select the **Set vertical steel settings** check box. 3. Set **L1** for the bottom level and **L2** for the top level. 4. Click **OK**. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(68).jpg) 3. Steel fitting requires two clicks. Click the upper and bottom points of the selected steel column. ![2f1de916-b7e0-4379-bdcf-e170e8e615e6.jpg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/2f1de916-b7e0-4379-bdcf-e170e8e615e6.jpg)![b0e23129-679d-4f33-ba67-46e378ce4d21.jpg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/b0e23129-679d-4f33-ba67-46e378ce4d21.jpg) 4. Review the catalog options and select the most appropriate one for the extracted steel geometry. Then click **OK**. > [!NOTE] > When we use the Catalog option, CloudWorx matches the point cloud to the best fit from a catalog of families loaded when the command is first initialised in the project. > > The initial guess is marked with an asterisk. You can scroll the catalog to find a better fit if needed. > > On the right side of the panel, a cross section of the cloud is overlaid with a magenta line showing the selected steel's cross section. Micro-adjustment arrows above the right panel let you adjust the fit if the cloud is noisy. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(69).jpg) 5. Repeat Steps 19-20 to extract more columns. 6. Now, let's take a look at the example of a poor fit, which requires some adjustments. To fix it, click the up arrow multiple times until the magenta fit line aligns with the cloud. Click **OK** to save the changes. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(70).jpg) 7. To exit the command, press **Esc**. 8. In the **Rendering** panel, click **Point Visibility** to hide the point cloud and review the extracted steel columns. ![](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/user_cropped_screenshot(71).jpg)
