Fit Wall

The FIT WALL tool aims to speed up wall modelling in Revit using point cloud data and automatically executes the following steps:

1. Model a wall in 3 clicks

2. If the Revit model already has a wall of this width, this tool will insert it.

3. If it doesn’t find a wall of that width, it will automatically create one based on the accuracy step you set.

4. With the Chain Wall option enabled, you can continuously model wall chains.

Fit wall tool settings:

Wall Type Choose an existing wall type.
Location Line Choose the line that represents the baseline or reference line of a wall.
Base & Offset Choose the base level of the wall and adjust its offset if necessary.
Top & Offset Choose the Top level of the wall and adjust its offset if necessary.
Create New Type A new wall type will be automatically created if the width exceeds the chosen type by the defined step.
Step Step for creating new wall type.
Chain Wall Automatically joins walls created sequentially, one after another.
4 Point Arc Wall Let you draw an arc wall by choosing the fourth point.
Naming (New Type) Specify a name for automatically created walls.


NOTE: To change settings, press ESC once; to exit “Fit Wall,” press ESC twice.

Align Walls and Columns

This tool is designed to help you align elements such as walls and columns more accurately within your project, ensuring a clean and precise model.

Step 1: Selection and Activation

Select Elements: First, select all the walls and columns you want to align. Then select the desired elements in the plan view.

Activate Tool: With the elements selected, click on “Align Walls and Columns” from the toolbar or menu.

Step 2: Analysis and Adjustments

Review Element Deviations: After activating the tool, a popup will appear displaying a 3D view of your elements with color-coded indicators:

    • Light Green: Elements are already aligned.
    • Darker Green, Yellow, or Orange: Elements can be aligned but have deviations.
    • Red: Elements cannot be aligned due to exceeding tolerance limits.

Set Project Tolerances: Within the tool settings, define your project’s tolerance levels for linear and angular deviations. Standard defaults are 30 mm for linear and 5° for angular deviations.

Step 3: Alignment Options

Choose Alignment Method: The tool offers several alignment methods:

    • Auto Axis: Automatically aligns elements based on their axes.
    • Grids: Aligns elements to existing grid lines.
    • Project North: Aligns elements to the project’s north direction.
    • Select Walls: Aligns elements to specific walls chosen by the user.

Perform Alignment: Depending on the selected method, execute the alignment process. Adjust the maximum deviations and click “Align Elements.”

Step 4: Review and Adjustment

Address Warnings: Review any warnings or issues flagged by the tool after alignment.

    • Elements slightly off-axis may be highlighted for manual adjustment.
    • Check for broken connections or trim/extend issues.

Fine-tuning: If needed, adjust tolerance settings and realign elements until deviations are within acceptable limits.

Step 5: Final Checks and Completion

Finalize Alignment: Once satisfied with the alignments, finalize the process.

    • Ensure critical elements like walls are aligned accurately for future detailing (e.g., window placements).

Best Practices:

  • Early Alignment: Align walls and columns early in your project workflow to avoid compounding issues later.
  • Regular Checks: To maintain accuracy, periodically check and realign elements as your project progresses.

Following these steps and best practices, you can use the “Align Walls and Columns” tool to create a clean and precise Revit model, facilitating easier dimensioning and overall project success.

Auto Floor & Ceiling

1. Setting Up the Rooms and Annotations

Start by setting up the rooms and gathering height annotations for each floor.

  • Create a Raster image.
  • Create Rooms: Architecture -> Rooms -> Select rooms.
  • Add Height Annotations: Use the annotation tool to mark the Height of each floor. Click on the annotation spot in the image to specify the floor heights.

2. Using Auto Floors for Creating Floors

Now that we have our rooms and floor heights annotated, we can proceed to create the floors automatically.

  • Auto Floors Tool: Click “Auto Floors and Ceiling” from the toolbar.
  • Choose Floor Type: Select the type of floor you want (e.g., 100 mm floor) and choose “Floors.”
  • Generate Floors: Specify the floor (e.g., ground floor) and click “Create.” Revit will generate floors for each room based on the specified heights.

3. Verifying the Created Floors

After generating the floors, it’s crucial to verify them to ensure accuracy.

  • Cross-Check Using Sections: Make a section through the rooms to verify the generated floors and create a raster image.

4. Creating Ceilings Using Auto Ceiling

You can use a similar process to create ceilings.

  • Prepare Wireframe: Set up a wireframe view for the ceiling and create a ceiling raster image.
  • Update Annotations: Remove previous annotations and add new ones for ceiling heights.
  • Access Auto Ceilings Tool: Click “Auto Floors and Ceiling” and select “Ceilings.” Choose the ceiling type and specify the ceiling layer. Click on “Create” to generate ceilings for the rooms.

5. Verifying the Created Ceilings

  • Inspect in Sections: Make sections through the rooms to check the ceilings.

Using the Auto Floors and Ceiling tool in Revit is a quick and efficient way to generate floors and ceilings for rooms in your design projects, especially for simple residential layouts.

By following these steps, you can streamline the process of creating separate floors and ceilings for each room without extensive manual intervention.
