How to Edit a Mullion Profile in Revit?

Understanding Mullion Profiles in Revit

Mullions serve as structural elements in curtain walls, providing both aesthetic appeal and functional separation of glass panels. When using Revit, knowing how to modify the profile of a mullion can enhance your design’s overall look and ensure it meets project specifications. The following guide will lead you through the step-by-step process of editing a mullion profile effectively.

Step 1: Accessing the Curtain Wall

To begin, locate the curtain wall that contains the mullion you wish to edit:

1. Open your Revit project and navigate to the view where the curtain wall is visible.
2. Select the curtain wall panel to activate the modification options.

Step 2: Entering Edit Mode for the Mullion

Next, you will need to access the properties of the selected mullion:

1. Click on the “Modify” tab that appears when you select the curtain wall.
2. In the “Curtain Panels” section, find and click on "Edit In-Place." This action lets you make changes directly to the curtain wall elements.

Step 3: Selecting the Mullion to Edit

With the edit mode activated, locate the specific mullion you want to change:

1. Click on the mullion to select it. Ensure that it is highlighted to confirm your selection.
2. If multiple mullions exist, be careful to choose the correct one—check for proper alignment and positioning.

Step 4: Modifying the Mullion Profile

Now, it’s time to edit the mullion’s profile:

1. Go to the “Properties” palette, which typically appears on the left side of your workspace.
2. Click on “Edit Type” within this palette. This option will open the Type Properties dialog box.
3. In the dialog, look for the field labeled “Construction.” Under this category, you’ll find an option to select or change the profile of the mullion.
4. Click the drop-down list and choose a new profile from the available options or create a custom profile by importing one if needed.

Step 5: Saving Changes

Once you’ve made the desired modifications to the mullion’s profile:

1. Click “OK” to apply the changes and exit the Type Properties dialog box.
2. Finally, be sure to click “Finish Edit Mode” to finalize your adjustments to the curtain wall.

Troubleshooting Common Issues

If the mullion does not appear as expected following edits:

• Check if the curtain wall panel was previously constrained or if there are other parameters limiting the profile.
• Ensure the profile you selected is appropriate for the current mullion type.

Frequently Asked Questions

1. How do I create a custom mullion profile in Revit?
To create a custom mullion profile, use the Family Editor in Revit. Load a profile from a CAD file or create a new one using sketch tools, then save it in the RFA format before loading it into your project.

2. Can I apply different profiles to different segments of a mullion?
Yes, Revit allows you to assign different profiles to various segments of a mullion. This can be done by selecting each segment and changing its type in the Type Properties dialog.

3. What should I do if a mullion won’t resize correctly after editing?
If a mullion won’t resize as intended, ensure that there are no constraints affecting it within the design. You may also need to check the alignment settings for the curtain wall to correct any issues.
