In my post last week, My Model is Finished, Now to Add The Decals, I showed you how to use the Decal tool in Autodesk Revit software to apply a raster image into 3D views and Renderings for use as television screens, building signage, photographs, and paintings. I want to take that one step further now and show you another use for decals, lettering on glass.
With standard decals, a Source image is added to a Decal Type with the decal in turn being added to a surface. When creating the appearance of lettering on glass, two image files need to be used:
1. One that is considered the Source image and will represent the lettering or symbol “painted” on the glass
2. One that will be used as a mask, or in decal terms, a Cutout.
The Source image will generally include any lettering or symbols against a transparent background. Most photo editing programs will allow you to create an image that includes the transparent color. In the image below, the checkered pattern indicates the transparent background.
Note: Just using a Source image with a transparency is not enough to create the lettering effect.
The Cutout image is used as the mask for the Source image, and it is black and white. The black portion of the image is the transparent area from the Source image and will not display when applied to a surface in Revit. The White area is the “Cutout” of the mask where the text and symbols of the Source image will be placed.
To create the decal, use the Decal Types tool found in the Insert tab>>Link panel>>Decal flyout>> Decal Types tool.
In the Decal Types dialog, select the Create New Decal icon (see image below) to create a new decal. For the Source image, which will be the actual decal/image applied to the glass, pick the […] beside the Source to select the Source image to be used.
At the bottom of the dialog, choose the Cutouts drop-down menu and select “Image file” from the list. This will display a Source box similar to the Source box at the top of the dialog box. Pick the […] to select the image that will be used as the Cutout.
After the Decal Type is created, use the Place Decal tool to add the type to a glazing surface. Once rendered, you should have what appears to be lettering on glazing.
Cutouts can also be used to mask any image for portions of the image you do not want to show up in your Rendering. In the following example, an Image and a Cutout was used to place Graffiti on a building.
To see this workflow in action, watch my video, Creating Lettering on Glass.
Have fun working with decals and making your renderings dynamic.

In my post From Napkin Sketches to Revit, I showed you how to use the image command to apply a raster image of a napkin sketch, add it into your Revit model, scale it, and use it as a background to trace over to create a BIM model. In that post, I mentioned images could only be added to 2D views, but by using the Decal tool in Autodesk Revit software, an image can be used within 3D views and perspectives.
The Decal tool can be a helpful tool when the desired effect is to use an image to enhance your model. Decals can be used to display a client’s signage on a building, a painting in an office or living room, a football game on TV, or even your business name lettered on a glass door, and it is typically used when rendering a model.
Working with Decals:
The Decal tool can be found in the Insert tab. This tool is a dual functioning tool; pick the bottom portion of the tool to flyout the two tools related to decals.
The Decal Types tool is used to create and configure a decal for use in the model.
In the Decal Types dialog box, new decals can be created, duplicated, renamed, and deleted. The list on the left contains any decals configured in the project.
The settings on the right side of the dialog box control various settings for the selected decal from the list on the left. Settings such as Selecting an image to use a decal, the Brightness, Reflectivity, Transparency, and Finish of the decal can all be controlled here.
After a decal has been created and configured, use the Place Decal tool to place the decal on a flat or curved surface. Note that the decal image will be visible when using a Realistic visual style and when rendering. If you are using a visual style other than Realistic, the decal will not show at the time you add the decal.
At the time, you add the decal to a surface, the decal boundary appears, and it will adjust to either a curved or a flat surface. Keep in mind, the decal is designed for use in a rendering. Although it will display when using the Realistic visual style, the boundary of the decal will appear.
Images and the Image tool are used to display the image in a 2D view such as a plan and elevation view. Decals can be used in 3D views and are typically effective when the 3D view is rendered, otherwise the Realistic visual style will display the decal boundary.
So there you have it, use Decals to enhance your renderings by helping them be a bit more realistic, incorporate logos or images that would not be able to be used by using the Image command.
To get a closer look at this workflow, watch my accompanying video, My Model is Finished, Now to Add the Decals.
