To edit a curtain grid in Revit, you'll primarily be using the "Curtain Grid" tool and instance properties modification. Here's a breakdown of the process:
1. Accessing the Curtain Grid Tool:
- Open a 3D view or an elevation view where the curtain wall is visible.
- Go to the "Architecture" tab on the Revit ribbon.
- In the "Build" panel, click "(Curtain Grid)".
2. Placement Types:
After activating the "Curtain Grid" tool, you'll see the "Modify | Place Curtain Grid" tab. Within the "Placement" panel, you can choose from the following placement types:
- All Segments: This places a grid line across the entire curtain panel.
- One Segment: This places a single grid line segment.
- All Except Picked: This places grid lines across the whole panel except where you click to remove them.
3. Placing Grid Lines:
- Move the cursor along the edges of the curtain wall panel. Revit will display a temporary grid line preview.
- Click to place the grid line. The location depends on the placement type selected.
4. Modifying Existing Grid Lines:
- Selecting Grid Lines: Hover over a grid line until it highlights, then click to select it. You might need to use the Tab key to cycle through selections if multiple elements are close together.
- Moving Grid Lines: Once selected, you can drag the grid line to a new position. Temporary dimensions will help you place it accurately. You can also use the "Move" command on the Modify panel.
- Adding/Removing Segments: To add or remove segments within a single grid line, select the grid line and use the "Add/Remove Segments" tool on the Modify | Curtain Grid tab. Click the segments you want to add or remove.
- Changing Grid Line Properties: Select the grid line and then access its instance properties in the Properties palette. You can modify parameters like offset, angle, and visibility.
- Pinning/Unpinning: Use the "Pin" tool (on the Modify panel) to lock a grid line in place. Unpin to move it again.
- Deleting Grid Lines: Select a grid line and press the Delete key or click the "Delete" button on the Modify panel.
5. Working with Curtain Wall Mullions
Keep in mind that when you edit curtain grids, the associated mullions will adjust accordingly. You may need to modify mullion properties (type, profile, etc.) separately.
Example:
Let's say you want to add a horizontal grid line halfway up a curtain panel.
- Select "Curtain Grid" tool.
- Choose "All Segments" placement type.
- Hover near the vertical edge of the panel, approximately halfway up. Revit will show a preview of the horizontal grid line.
- Click to place the grid line.
Troubleshooting:
- If you're having trouble selecting a grid line, try using the Tab key to cycle through selections.
- Ensure the curtain wall is not pinned or locked in a way that prevents editing.
- Check the visibility settings to ensure grid lines are visible in the current view.
By understanding these steps, you can effectively edit curtain grids in Revit to achieve your desired design.
