Shapes can be drawn in the PDF editor either at a document level or bundle level. More guidance on opening documents or bundles in the PDF editor can be found here.
With your document open in the PDF editor, first select the "Line" tool in the ribbon, and select your required shape. These include:
Rectangle
Ellipse
Polygon
Cloudy Polygon
With your chosen shape selected you can click and drag over your PDF to draw the shape.
Before drawing on your shape, you can change the line colour, line thickness, line opacity, and line type using the sub-ribbon.
