Lines and arrows 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 "Line" or "Arrow".
With the line or arrow tool selected, you can click and drag over your PDF to draw a line or arrow.
Before drawing on your document, you can change the line colour, line thickness, line opacity, blend mode and arrow type using the sub-ribbon.
