Using the ARC command

I have spent yesterday afternoon and this morning trying to understand how

to use the ARC command on the command line with no luck. All I want to do

is to draw and arc of radius 0.5" centered at 0.5", 1.7" with a specific

line width.

The eagle manual is of no help because the description of the command is

too cryptic for me to understand. Can anyone help me understand how to do

this?

 

Any enlightenment will be appreciated.

Hi Vic,

there are various options, for example:

Set a relative origin first and then use the WIRE command which can draw

arcs as well. You can use for example polar coordinates.....

MARK (0.5 1.7);            # relative origin

WIRE (P 0.5 0)  @+0.5  (P 0.5 90);   # polar starting point, radius,

                                        ending point of the arc

inside ( ):  P for polar coordinates,

              first value: radius from the origin, second: angle)

2nd example with relative coodinates:

  MARK (0.5 1.7);            # relative origin

  WIRE (R0 0.5)  -90  (R0.5 0)    # relative starting point, curve,

                                    relative ending point

Please see details about the syntax with radius and curve in the help of

the WIRE command and Editor Commands/Command Syntax.

I hope this helps.
