Revit Model Splitting Based on Project Requirements
In Revit, the electromechanical model is typically divided into three main categories according to project needs: water supply and drainage, HVAC, and electrical. Using the electrical system as an example, similar steps apply to other disciplines. This approach facilitates easier model separation when different requirements arise or when working with a single professional model. The process mainly involves two key steps: grouping and saving.
1. Grouping
Start by creating a view plan for each discipline based on your project drawings, as illustrated below.
Step 1: Electrical Grouping
Open your project and switch to a 3D view. Then, open the Visibility/Graphic Overrides dialog box. Under the Model Categories tab, select Filter List and choose Show All. Click Select All, then uncheck everything and confirm your selection, as shown in the image.
Step 2: In the Filter List, select Electrical, check all relevant options, and click Confirm. This will hide all non-electrical components, as demonstrated in the figure.
Step 3: Select all electrical components, then go to the Modify tab and click Create Group. You may encounter an error message indicating that some components have lost their association with their host due to being hosted. Simply click Confirm, as shown.
Step 4: A dialog box will appear to create the model group. Rename the group to Electrical, as illustrated.
Step 5: Rename the corresponding 3D view to Electrical Split in the Project Browser. The updated view effect after these modifications is shown in the image below.
Step 6: Repeat the above steps to split other disciplines. You can also customize the associated plan views, elevation views, section views, and 3D views for each professional category accordingly.
2. Saving
Step 1: Save the entire combined model first. Then, based on this original model, save each grouped model separately to complete the splitting process. For example, when saving the electrical model, include elements from plumbing, fire protection, HVAC, and any unused categories. Since many unused items accumulate during modeling, including them helps reduce memory usage, as shown in the illustration.
Step 2: Name the file accordingly, such as Electrical Split – Second Floor of XXXX Project. Repeat this for other disciplines. The final folder structure for the mechanical and electrical model split is depicted in the figure below.
Summary: Breaking down the professional models in this way makes it easier to generate, manage, and modify models for each discipline, thereby optimizing project workflows.
