Page 10 of 17		    USING ACROTRAN

AcroTran is a program on the diskette that allows you translate DXF files into
AcroSpin files.  DXF files are commonly used to transfer graphics data between
different programs, such as computer aided design packages.  AcroTran supports
DXF files compatible with AutoCAD Releases 9 or 10.  AutoCAD is the computer
aided design package produced by Autodesk, Inc.

The next object, a robot arm, was translated from an example that comes with
AutoCAD.  After creating a DXF file called ROBOT.DXF, it was translated to
AcroSpin format by the command ACROTRAN ROBOT.	This produced an AcroSpin
file called ROBOT.ACD.	The default file extension for AcroSpin files is ACD.

One of the handy options for AcroTran is the ability to specify the number of
line segments used to approximate circles.  By default, circles are
approximated with 8 line segments.  If you had a file called CIRCLE.DXF, you
could translate it to an ACD file using 42 segments to approximate the circle
by using the commands ACROTRAN CIRCLE SEGMENTS 42 or ACROTRAN CIRCLE SEG 42.
Arcs are approximated proportionately.

AcroTran preserves the layer information in the original DXF file, assigning
the layers consecutive numbers starting with 0. The robot arm has 11 layers,
numbered from 0 to 10 (layer 0, however, is empty).
