Layer Property Overrides
If you convert an AutoCAD 2008-based drawing containing layer property
overrides, the overrides are not visible in previous releases. The property
override settings are retained when the drawing is saved in a previous release,
and are visible again when the drawing is opened in an AutoCAD 2008-based
product.
For previous releases of AutoCAD-based products, if the VISRETAIN system
variable was set to 0 when the drawing was saved, xref layers containing
viewport property overrides are not retained when opened in DWG TrueView.
If you open an AutoCAD 2008-based drawing in a previous release, property
overrides might display in a thumbnail image. When the drawing is saved
with a layout tab, and then opened in the previous release, those property
overrides do not display.
Multiline Text Objects
Some of the paragraph spacing and paragraph line spacing options are not
supported when an AutoCAD 2008 multiline text object is opened in AutoCAD
2007 and earlier releases.
The following multiline text formatting features have no visual fidelity in
previous releases:
Paragraphs with justified alignment
Paragraphs with distributed alignment
Fields that wrap across columns
Fields that wrap across lines that have new paragraph alignments
Paragraphs with non-default alignments in multiline text without left
object-level justification
The following multiline text formatting features have some visual fidelity in
previous releases (when its possible to add white spaces or replace text with
white spaces):
Paragraphs with non-default alignments (other than justified or distributed)
in multiline text that has left object-level justification
Paragraphs with tabs using tab alignments (center, right, or decimal
alignment applied)
Paragraphs with line spacing that can be approximated with tall spaces
