to DWG Conversion Table

Notes
|
| Geometric Elements |
Geometric Objects |
The following DGN elements are translated into
DWG objects: line, SmartLine, LineString, 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.
|
| Levels |
Layers
|
DGN levels are mapped
automatically into the equivalent DWG layers. Invalid DGN characters
in level names are converted to spaces.
|
| Colors |
Colors |
All colors are translated using RGB values either
to the ACI (AutoCAD Color Index) or TrueColor index as appropriate.
|
| Line Styles |
Linetypes |
Only simple line styles
using solid lines, dashes, and dots are supported. Unsupported custom
line styles are converted into continuous linetypes.
Dynamically scaled line
styles are converted into fixed-scale linetypes. The resulting linetypes
use a scale near the middle of the scaling range of the dynamic
line style.
NoteTo import standard
V7 line styles correctly, you must “Fit View” and “Save Settings”
in MicroStation first.
|
| Cells |
Blocks
|
Cells are converted into
blocks. Tags that are associated with cells are converted into constant-mode
block attributes.
|
| Text Elements, Text Styles |
Single-line Text Objects, Multiline Text Objects, Text Styles |
Missing SHX text fonts are converted into the AutoCAD text
font specified in the FONTALT system variable. The acad.fmp file can be used to map
SHX text fonts to DGN text fonts. TrueType fonts and SHX
fonts in AutoCAD are exported to MicroStation V7 as Engineering. This
can result in many visual differences.
|
| Tables |
Tables |
Cells that represent tables in DGN are imported as blocks. |
| Dimensions, Dimension Styles |
Dimensions, Dimension Styles |
The size, spacing, style, and shape of dimensions may
vary slightly. Dimension associativity is maintained whenever possible, and
the correct dimension values are always maintained.
|
| Fields |
Fields |
In general, fields are
translated as static text. The exceptions are fields that behave identically
in both products. This includes the Date fields CreateDate, SaveDate,
and PlotDate, and the Document property
fields Author, Filename, and Filesize.
Fields are converted
to text when “Explode Text Nodes to Text Elements” is checked in the
Import DGN Settings dialog box.
|
| Raster Images |
Raster Images |
These image file types: .bmp, .cal,
.tif,
.png, .tga,
.jpg,
.pcx, .gif, .rlc, .bil,
and .pct are supported. All other image
file types are not.
|
| DGN References |
DWG References |
.dwg and .dgn file types
are supported. Other non-DGN file types such as .cel, .h, .s, .d,
.rdl, and .cgm are also supported.
|
| DGN Design Model |
DWG Model |
The selected design model in a DGN file is converted
into a DWG file.
|
| DGN Sheet Model |
DWG Layout |
Only the sheet models that reference the primary design
model are imported. DGN sheet models are translated as layouts in
a DWG file.
