Identifying the Component
Identifying the correct component in Revit is crucial for making any changes or modifications. There are various ways to identify components, each with its own advantages and disadvantages. Choosing the appropriate method depends on the specific situation and the desired level of detail:
Element ID
The Element ID is a unique identifier assigned to each element in the Revit model. It is a reliable way to identify components, especially when working with linked files or external references. To find the Element ID, select the component, right-click, and choose “Properties.” The Element ID will be displayed in the “Properties” dialog box, under the “General” tab.
Element Name
The Element Name is a user-defined name that can be assigned to components. It is typically used to provide additional information or context about the component. To find the Element Name, select the component, right-click, and choose “Properties.” The Element Name will be displayed in the “Properties” dialog box, under the “General” tab.
Type
The Type of component refers to its specific characteristics and properties. It determines the behavior and appearance of the component within the model. To find the Type of a component, select the component, right-click, and choose “Properties.” The Type will be displayed in the “Properties” dialog box, under the “Type” tab.
Category
The Category of a component groups it with similar elements in the model. It helps organize and manage the components within the project. To find the Category of a component, select the component, right-click, and choose “Properties.” The Category will be displayed in the “Properties” dialog box, under the “General” tab.
| Method | Advantages | Disadvantages |
|---|---|---|
| Element ID | Unique identifier; reliable | Not user-friendly; can be difficult to remember |
| Element Name | User-defined; provides additional context | May not be unique; can be changed |
| Type | Specific characteristics and properties | Can be complex for non-familiar users |
| Category | Grouping and organization | May not provide enough detail |
Right-clicking the Component
Alternatively, you can make changes to a component’s properties by right-clicking on it. Right-click the component and select **Properties** from the context menu. This will open the **Properties** dialog box, which displays the following information:
- The component’s name
- The component’s type
- The component’s dimensions
- The component’s material
- The component’s color
- The component’s properties
You can make changes to any of these properties by simply typing in the new value. Once you have made your changes, click **OK** to save them.
If the component is part of a group, you can right-click on the group and select **Ungroup**. This will break the group apart and allow you to make changes to the individual components.
| Property | Description |
|---|---|
| Name | The name of the component. |
| Type | The type of component. |
| Dimensions | The dimensions of the component. |
| Material | The material of the component. |
| Color | The color of the component. |
| Properties | The properties of the component. |
Selecting “Edit Family”
Within the Edit Family task, you’ll find two sub-options: Project and Current Project.
Project
This option opens the family in the project context. This means that you’ll be able to see the family as it’s used in the project, with all of the project’s parameters and settings applied. This is useful for making quick edits to a family that are specific to the project, without having to open the family in a separate file.
Current Project
This option opens the family in a new file, isolated from the project. This is useful for making more extensive edits to a family that will be used in multiple projects, or for creating a new family from scratch.
When you select either of these options, the Family Editor interface will appear. This interface is similar to the Revit interface, but it has some specialized tools and features for working with families.
The following table summarizes the key differences between the Project and Current Project options:
| Option | Description |
|---|---|
| Project | Opens the family in the project context, with all of the project’s parameters and settings applied. |
| Current Project | Opens the family in a new file, isolated from the project. |
Modifying the Family
Modifying the family is a crucial step in customizing Revit components. Here’s a detailed guide on how to do it:
1. Open Family Editor
Launch Autodesk Revit and navigate to the “Manage” tab. Click “Family Editor” to open the editing workspace.
2. Select and Modify Elements
In the Family Editor, select the element you want to modify. Use the “Properties” palette to adjust properties such as size, shape, and material. You can also use the “Modify” tab to make more specific changes to the geometry or constraints.
3. Create or Modify Parameters
Parameters allow you to control the behavior of the family in the project environment. Create new parameters or modify existing ones to adjust the component’s dimensions, materials, or other attributes.
4. Create Constraints
Constraints define the relationships between elements within the family. They ensure that elements maintain their positions and relationships as the component is used in the project. To create a constraint, select the elements and click on the “Constraints” tab. Choose from various constraint types, such as distance, angle, or alignment.
| Constraint Type | Description |
|---|---|
| Distance | Controls the distance between two elements. |
| Angle | Controls the angle between two elements or planes. |
| Alignment | Aligns elements along a common axis or plane. |
| Lock | Prevents an element from moving or rotating. |
| Equal | Sets the dimensions of two elements to be equal. |
Saving the Changes
Once you have made your changes to the component, you need to save them. To do this, click on the “Save” button in the “Component Properties” dialog box. This will save the changes to the component itself, but not to the project file. To save the changes to the project file, you need to click on the “Save” button in the “Project” tab of the “Ribbon”.
If you have made changes to the component that are not compatible with the existing project file, you will be prompted to save the component as a new file. If you choose to do this, the changes you have made will be saved to a new file, and the original file will remain unchanged.
Here is a summary of the steps involved in saving changes to a component:
| Step | Action |
|---|---|
| 1 | Make your changes to the component. |
| 2 | Click on the “Save” button in the “Component Properties” dialog box. |
| 3 | If prompted, save the component as a new file. |
| 4 | Click on the “Save” button in the “Project” tab of the “Ribbon”. |
Reloading the Family into the Project
In some cases, you may need to reload the family into the project to update the components. Here’s a step-by-step guide on how to do it:
Step 1: Unload the Family
Open the Project Browser and select the family that you want to reload. Right-click and select “Unload Family”.
Step 2: Reload the Family
Go to the “Manage” tab in Revit. Select “Load Family” and browse to the family file (.rfa) that you want to reload.
Step 3: Select the Components to Replace
Once the family is loaded, a dialog box will appear asking you to select which components you want to replace. You can choose to replace all instances of the family or only specific instances.
Step 4: Replace the Components
Click on the “Replace” button to replace the selected components with the updated family. Depending on the size of the project and the number of components being replaced, this process may take some time.
Step 5: Review and Resolve Any Errors
Once the replacement is complete, Revit will check for any errors. If there are any errors, you can review them in the “Issues” tab of the Project Browser and resolve them as necessary.
Step 6: Check the Properties of the Components
To ensure that the components were updated successfully, it’s a good practice to check their properties. Select a few components and open the Properties dialog box (Properties tab > Properties). Verify that the family name and other properties are correct.
| Property | Value |
|---|---|
| Family Name | Updated Family Name |
| Type Name | Updated Type Name |

- Select the component you want to match.
- Click the Eyedropper tool in the Modify panel on the Home tab.
- Hover over the target component and click to apply the properties.
Matching Specific Properties
By default, the Eyedropper tool will match all of the properties of the selected component. However, you can choose to match only specific properties by using the Property Filter drop-down list in the Options bar.
| Property | Description |
|---|---|
| Graphics | Matches the visual appearance of the component, including its material, color, and texture. |
| Geometry | Matches the size and shape of the component. |
| Parameters | Matches the parameters of the component, such as its dimensions and properties. |
| Identity Data | Matches the unique identifier and other identity data associated with the component. |
Matching Components from Different Sources
The Eyedropper tool can also be used to match components from different sources, such as imported files or linked models. This is useful when you want to ensure that the components in your project have a consistent appearance or when you need to replace components from a specific source.
- Open the file or model containing the target component.
- Select the target component and click the Eyedropper tool.
- Hover over the corresponding component in your project and click to apply the properties.
Rehosting Components
Rehosting components involves moving them to a different host element or family. This can be useful for organizing your model or for changing the way components interact with each other.
Steps to Rehost a Component
- Select the component you want to rehost.
- Right-click and select “Properties.”
- In the “Properties” dialog box, click the “Rehost” tab.
- Select the new host element or family.
- Click “OK” to rehost the component.
Additional Notes
- Only certain types of components can be rehosted. For example, you can rehost families, symbols, and groups, but you cannot rehost walls or floors.
- When you rehost a component, its position and rotation will be updated to match the new host element. However, its other properties, such as its materials and finishes, will remain the same.
- You can use the “Rehost” tab in the “Properties” dialog box to view a list of all the components that are hosted by a particular element.
Troubleshooting
If you are having trouble rehosting a component, try the following:
| Problem | Solution |
|---|---|
| The component cannot be rehosted to the selected host. | Make sure that the component is compatible with the host element. For example, you cannot rehost a family that was created for a wall to a floor. |
| The component is not moving to the correct location when it is rehosted. | Check the “Location” settings in the “Rehost” tab of the “Properties” dialog box. |
