How do I make rectangle align side with curve?

I am just learning autocad 2004, and have a question. I am currently
working in 2d, and have a rectangle, and a shape I created subtracting a
half circle from a square. So I have this small rectange
(representing 2x4's) which I need to have the short side moved and
rotated to have one face tangent along the face of curve. I also would
like to have the 2x4's spaced every 6" along the curve if there is a way
to do that also.
Thanks,

Look into the ARRAY command. Use the POLAR option.

 

I see know how I can use the ARRAY command with the polar option
to do the stud spaced around curve. How do I determine how many
degrees will give me 6" spacing?
Thanks,

HiHo;
Length=Radius * AngleInRadians
or
Chord/2*Radius=sin1/2AngleInDegrees

Hope this helps.

 

That's a GEOMETRY question, and not a very clear one at that.
Are your '6" spacing' radial or along the curved path? Are they from
tip-to-tip
or center-to-center?
Paul's suggestion will do the job if you aren't very good with geometry.
The insertion point of the block becomes critical if you use MEASURE, as you
will see....

 

I am the original poster on another account. I am referring to having
2x4 studs spaced with 6" centers along the curve path. I have created
a 2x4 block already.
