In AutoCAD, you can adjust the transparency value of any type of object including text, lines, images and hatching. Transparency is controlled in the properties of selected objects and can also be set to a default value for new objects. Transparency effects can be used to enhance your drawings in a variety of ways, for example, by making a hatch transparent you are able to show objects that may otherwise be hidden below the hatch. Transparency can also be used to de-emphasize linework and objects that are meant for reference, removal, or simply less important to the visual goal of your drawing.

Object and Layer Transparency: Transparency by Layer

Here are a few ways you can use Transparency effects in your AutoCAD drawings.

Hatches

You can set the transparency value of a hatch directly from the Hatch Creation Ribbon tab. By using the slider or entering a specific value in the hatch field you can adjust exactly how transparent your hatch will be, allowing you to control how much or how little objects below the hatch will be visible. Existing hatch transparency can be adjusted by selecting the hatch to automatically bring up the contextual Hatch Editor Ribbon tab and then setting the transparency value as desired.

In the example below, the Hatch Editor is being used to add transparency to an existing hatch in order to highlight different areas while still showing the objects underneath.

Layers

One of the easiest ways to use transparency in your drawings is to apply a transparency value to an entire layer or layers. Once set, all of the objects on the layer will maintain the same transparency value unless manually changed in the properties tab. This will allow you to create layers that are less visible to indicate they are intended for reference or less important visually to the drawing.

In the image below, the interior walls and furniture have been placed on the reference layer with a transparency value set to 50.

Selected Objects

If you would like to set the transparency of an individual or group of selected objects, you can do so by right-clicking and choosing properties. Once the properties palette is open you can enter a number in the Transparency box from 0 to 90 percent to set the value for all of the selected objects. In this example the three Mtext labels have a transparency value of 70.
