multiline, shape, complex chain, complex
shape, arc, ellipse, curve, B-spline curve, and
pattern. Pattern elements are limited to simple
pattern styles. Bitonal gradient properties are
also supported.

spaces.
All colors are translated using RGB values
either to the ACI (AutoCAD Color Index) or
TrueColor index as appropriate.

Only simple line styles using solid lines,
dashes, and dots are supported. Unsupported
LinetypesLine Styles
custom line styles are converted into continu-
ous linetypes.
Dynamically scaled line styles are converted
into fixed-scale linetypes. The resulting line-
types use a scale near the middle of the scal-
ing range of the dynamic line style.
NOTE To import standard V7 line styles cor-
rectly, you must “Fit View” and “Save Set-
tings” in MicroStation first.
Cells are converted into blocks. Tags that are
associated with cells are converted into con-
stant-mode block attributes.
