PDF / Insert / Underlay

The PDF Underlay tool allows you to insert a page of a PDF file into your drawing to use as a reference or tracing layer. To use properly as a tracing layer, the file must be a vector PDF, rather than a bit-mapped PDF. As a vector file, you will be able to snap to the endpoints and midpoints of lines in the PDF underlay.

Underlays consist of two parts: the underlay style and the underlay insertion. Before inserting an underlay, you must first create an Underlay style, which is done through the Underlay Manager, found in the Tools menu of the Default interface, and in the Format menu of the Ribbon interface A new tool "PDF underlay to Objects" has been implemented. It gives the ability to convert an Underlay into an editable object.
