Here's the procedures we used with ArcInfo Librarian Layer of parcels converted to AutoCAD and maintain true curves.
This used ArcInfo Workstation v6.1.1/6.1.2/7 running on IBM's AIX v3.5 unix operating system, FTP, and AutoCAD Map 2.0 and AutoCAD R13 on Windows NT.
Reference:
topic 2.10.0 Arc/Info - Library prcl layer to Autocad program (maintain continuous curve)
Double-click on Exceed icon
Login to Lis_2
Open a terminal window
Change directories to /specialdata/public/dwg
Delete any existing homeprcl.dxf or homebase.dxf files
rm homeprcl.dxf homebase.dxf
Start Arc/Info & extract prcl layer
arc: workspace /specialdata/public/dwg
arc: librarian clovis-pdmanytile
librarian: settiles all
librarian: setlayers prcl
librarian: extract topological
librarian: quit
arc: copy prcl prcl.safe
Use Tables to add fields and populate FAT fields for: true curves, valid dxf values and street outlines
arc: tables
additem prcl.aat radius3 8 8 C #
SELECT PRCL.AAT
MOVE ‘PRCL’ TO DXF-LAYER
MOVE ‘CONTINUOUS’ TO DXF-TYPE
CALC DXF-COLOR = 7
MOVE RADIUS TO RADIUS3
RESELECT FOR RADIUS3 NC '[]'
CALC DXF-CURVE = 1
QUIT

arc: arcedit
arcedit: cogoenv prcl
arcedit: editfeature tic
arcedit: select all
arcedit: delete
arcedit: editfeature arc
arcedit: build
arcedit: save
arcedit: ASELECT FOR LPOLY# EQ 1 OR RPOLY# EQ 1
arcedit: PUT HOMEBASE
arcedit: unselect all
arcedit: quit
Convert coverage to exchange file
arc: arcdxf homeprcl.dxf prcl
arc: arcdxf homebase.dxf homebase
arc: kill prcl all
arc: kill homebase all
arc: kill prcl-safe all
arc: quit
Transfer to NT workstation for import to Autocad.
use exceed to ftp in binary from UNIX to NT workstation
use autocad map 2.0 file pulldown > open > type dxf
zoom extents, use units command to change to decimal, 4, surveyor, etc. and regen
save as R13 version for compatibility with existing network version of autocad program
Network File Server for public access
copy to citypub\basemap directory
