Opens the Markup Lister, which lets you create, manage and export Markups in a project. Markups let you draw directly onto the camera view, making it easy to share feedback on design projects.

By default, the size of the Markup created is based on the width and height of the window. This can be changed in the General Preferences under Markup.
Selecting a Markup will automatically display it and make it active for drawing. In tile view, hover on a Markup's thumbnail to access the opacity slider and visibility toggle.

The following image formats are available:
This option only appears when the File Type is .jpeg. Use the menu (Maximum, High, Medium or Low) or the slider (values from 1 to 100) to adjust the quality of the .jpeg image. A higher quality will result in a larger file size.
If checked, two sliders enable you to set (in pixels) the dimensions of the output image.
If this option is checked, the Vertical Size value is first adjusted so that the aspect ratio corresponds to that of the current window. Changing the horizontal or vertical size will then automatically adjust the other slider so that the aspect ratio of the image is preserved. This option only appears when Specify Image Size in on.
Size (in pixels) of the output image. These options only appear when Specify Image Size in on.
Markup workflows
Choose a brush from the Markup section in the Tool Palette.
The first time you click on top of the current view will create a Markup based on that view. You can now begin drawing freely.
To exit the current Markup and finish drawing on that Markup, rotate the view.

Images can be imported as a canvas which lets you place and transform them as planes. This is useful for setting up reference images that need to exist in the scene.
