Attach PDF Files
There are a few things specific to PDF files that you do not have to consider
with DWF or DGN files. PDF files with more than one page are attached one
page at a time (as opposed to one sheet at a time for DWF files or one model
at a time for DGN files). Also, hypertext links from PDF files are converted to
straight text and digital Signatures are not supported.
Drag Underlay Files
You can drag underlays directly into the drawing. Once you drag the file into
the drawing, you can enter
A sheet name (DWF and DWFx)
A page number (PDF)
Or a model name (DGN)
from the file at the Command prompt and then specify an insertion point,
scale factor, and rotation.
Attaching an Underlay Multiple Times
You can reattach an underlay multiple times, treating it as a block. Each
underlay has its own clip boundary and settings for contrast, fade, and
monochrome. However, you cannot bind an underlay to a drawing and you
cannot edit or modify the underlays content.
Layers in Underlay Files
If the underlay file contains layers, you can control how the layers display
after attaching the file. If the file does not contain layer information, the
Underlay Layers dialog box does not display any layer information.
Underlay Files in Xrefs
DWG file references (xrefs), in a drawing can include an underlay. In this
situation, objects in the underlay are visible in the parent DWG file.
