Which Revit versions do you support?

We only support the current released version of Revit along with the two previous versions.

If the current released version of Revit is 2024, the Revit add-in is supported for 2022 and 2023. Previous versions of Revit can be compatible with the add-in, however there might be stability issues, so use with caution.

What if my Revit add-in dashboard disappears or is blank?

There are a couple of things to try when the dashboard disappears or is blank:

• Try logging out and back in using the Settings button.

• If the dashboard is blank, close it using the X and re-open it using the Dashboard button.

• If none of the above works, navigate to %AppData%\\Roaming\\ and delete the Layer folder. Then re-install the Revit add-in from here. Follow the steps listed in the Revit add-in intro article.

⚠️ Remember: You can always reach out to our support team via chat in the app or email help@layer.team.

What can I do to reduce the size of my model?

Layer supports models up to 5GB. To reduce your file size or improve processing time, try these tips:

Purge your model before uploading to Layer

Purging removes unused families, views, and other content. You can find instructions here →.

Convert imported CAD or Image files to Links

Instead of importing CAD or images directly, link them to store the files externally and reduce model size.

Delete unused or redundant Views & Sheets

Remove unnecessary views or sheets to reduce model file size.

Simplify overly complex families

Replace highly detailed model families with simpler ones if their complexity is unnecessary.

What Revit parameters are supported in Layer?

Reading: Layer can read all Revit properties, including Type Properties, Instance Properties, and Shared/Project/Global parameters. Use a Display Revit Parameter Field to display Revit data in Layer.

Writing: Layer allows you to write data only to Instance, Shared, and Project Parameters. Type Properties are not supported at this time.

💡 To enable a Shared Parameter workflow, first create the Shared Parameter, assign a value in Revit, and then publish your model to Layer.

What Layer Fields map best to Revit Parameters?

Text

Text parameters are the most flexible for mapping Layer data to Revit parameters.

Compatible Layer Fields:

• Text Input – Concrete

• Number Input – 100

• Toggle Input – Yes

• Date Input – 01/01/2020

• Person Input – Jim Smith

• Select One Input – Closed

• Select Multiple Input – Concrete, Tile, Wood

• Related Element Input – Issue 1, Issue 20, Issue 31

• Single Range Input – 40

• Dual Range Input – 30,65

• Phone Input – 4021234567

• Email Input – example@email.com

Integer

If numbers mapped to Integer parameters contain decimals, they will be automatically rounded.

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number

Length

Length parameters are flexible in accepted values.

Compatible Layer Fields:

• Text (recommended) – allows entering units directly (e.g., 56'-6", 5600mm). Converts to the model’s unit system. Learn more →

• Number – value applies directly using the model’s current units (e.g., 56 = 56'-0" in feet-inches).

Area

Values apply using the model’s current unit system (e.g., 25000 = 25000 m² or 25000 ft²).

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number (no units)

Volume

Values apply using the model’s current unit system (e.g., 25000 = 25000 m³ or 25000 ft³).

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number (no units)

Angle

Values apply using the model’s current unit system (e.g., 23 = 23° or 23 rad).

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number

Slope

Values apply using the model’s current unit system (e.g., 23 = 23° or 23 rad).

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number

Currency

Values apply using the model’s currency unit (e.g., $1566.23 maps to local currency format).

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number (no commas or symbols)

Mass Density

Values apply using the model’s unit system (e.g., 1500 = 1500 kg/m³ or 1500 lbs/ft³).

Compatible Layer Fields:

• Number (recommended)

• Text – must convert to a number

URL

Compatible Layer Fields:

• Text (recommended)

Yes/No

Compatible Layer Fields:

• Toggle (recommended)

• Number – 0 or 1 (0 = false, 1 = true)

• Text – must equal true/false or yes/no

Multi-line Text

Compatible Layer Fields:

• Text Input – Concrete

• Number Input – 100

• Toggle Input – Yes

• Date Input – 01/01/2020

• Person Input – Jim Smith

• Select One Input – Closed

• Select Multiple Input – Concrete, Tile, Wood

• Related Element Input – Issue 1, Issue 20, Issue 31

• Single Range Input – 40

• Dual Range Input – 30,65

• Phone Input – 4021234567

• Email Input – example@email.com

Partially Supported Revit Parameter Types

Material or any Revit parameter referencing an Element

Currently, parameters referencing a Revit element (e.g., Phase Created or Level) can be modified if you know the Revit Element ID.

Steps:

1. Create a text field in Layer.

2. Create a rule mapping that field to the desired Revit parameter (e.g., Level).

3. Enter the Revit Element ID of the element to reference (e.g., 694 for Level 2). This updates the parameter accordingly.
