If a viewport containing layer property overrides is deleted when the drawing
is opened in a previous release, the override settings are not retained and are
not available when the drawing is opened in AutoCAD 2008.
When the VISRETAIN system variable is set to 0 when the drawing is opened
in a previous release, xref layers containing viewport property overrides are
not retained.
If you open an AutoCAD 2008 drawing in a previous release, property overrides
may 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.
Dimension Enhancements in Previous Releases
AutoCAD 2008 dimension enhancements are lost when they are edited in
earlier releases. If you don’t change these dimensions, they are restored when
you open the drawing in AutoCAD 2008.
The following dimension enhancements do not lose visual fidelity in previous
releases if they are not edited:
■ Dimension breaks
■ Jogged linear dimensions
■ Inspection dimensions
■ Angular dimensions that are dimensioned using the quadrant option
■ Arc extension lines for radial and diameter dimensions
Multileader Objects in Previous Releases
Multileaders display as proxy objects in releases prior to AutoCAD 2008. The
PROXYSHOW system variable controls the display of proxy objects in a
drawing.
MTEXT Paragraph and Paragraph Line Spacing in Previous Releases
Some of the new paragraph spacing and paragraph line spacing options are
not supported when an AutoCAD 2008 mtext object is opened in AutoCAD
2007 (and earlier releases).
The following mtext formatting features have no visual fidelity in previous
releases:
■ Paragraphs with justified alignment
