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.
For example, drawing A includes a DWF underlay showing some mechanical
details. You need the content of drawing A attached to your current drawing,
drawing B. If you attach drawing A as an external reference to drawing B, the
DWF underlay that was already attached to drawing A is also be present.
All of the property settings made to the underlay in the external reference,
such as clipping boundaries, appear as they do in the parent drawing.
