degree disc


Hi, I'm having a little trouble trying to draw this: http://lambrettiste.free.fr/documents/faisceau/disque_gradue.pdf
Basically a protractor. I'm having trouble 'nutting out' the array command.
Can anyone help me with a step by step.
cheers

1. Select the geometry to be patterned (hold down Shift key to select
multiples or use fence).
2. Select the Circular Pattern command
3. Set the parameters
4. Select center point to pattern around.

Here's how I'd do it:
Open New drawing.
Open 2dmodel space
Right click in Design tree/lay control
"New Layer" Call construction.
Draw two concentric Circles.
Draw a line from centre of the circle to 12 noon. (make sure it snaps to orthogonal)
draw a line from centre of circle to approx 10deg, snap to circle.
Dimension to 3 deg between the vertical line and other line.
Trim Appropriately.
select the 3 degree line and pattern in circular pattern (fly out menu with either
eight circles ina 2x4 rect or 6 circles at 60degree intervals) for 9 pieces at 24
degrees (snap centre to centre of circle, use -24deg if going wrong way)
select the pattern and the vertical line and pattern 12 times at 330degrees.
change layers and line type appropriately.
I got a feasible clock face from it.
You can do the pattern command allthe way around and then miss certain occurances,
should you desire, but this is how I'd have done it.
