Adjust Underlay Contrast, Fade, Monochrome, and Colors for
the Background
You can modify the contrast, fade, and monochrome settings of an underlay.
Also, so that the underlay is visible, you can adjust the underlay colors based
on the AutoCAD background colors.
Adjusting these settings does not alter the original file and does not affect
other instances of the underlay in the drawing. You can change the contrast,
fade, monochrome, and colors in the Properties palette when an underlay is
selected. You can also use the DWFADJUST, PDFADJUST, DGNADJUST, or
ADJUST commands.
If you change contrast, fade, and monochrome values, plotted output is
affected.
Adjust Colors for Background
Adjust Colors for Background controls whether the underlay colors are visible
against the drawing background color. The default setting of Yes indicates
that the background colors of the underlay and the drawing environment are
analyzed to see if they are both light or both dark, or is one dark and the other
light. When one background is light and the other dark, the colors of the
underlay are inverted so the underlay is displayed. If the setting is changed
to No, the original colors of the underlay are used. Depending on the
background colors, the underlay might not be visible.
To use the Properties palette to adjust the underlay contrast, fade,
monochrome, and background color setting
1 Double-click the underlay to display the Properties palette.
2 In the Properties palette, do one of the following:
Adjust the contrast by entering a new value.
Adjust the fade by entering a new value.
Turn Monochrome On or Off.
Set Adjust Colors for Background to Yes or No.
The appearance of the underlay is updated in real-time as you make
adjustments in the Properties palette.
