I just need a circle with lots of radii equally spaced.

WTF

I don't know how to do it and good isn't helping.

They didn't teach us this in A school.

[Edited on January 13, 2011 at 10:30 PM. Reason : of the polar variety]

I hate it when good doesn't help

look up polar array

1/13/2011 10:55:09 PM

shit

circle -> dia = 27"
polyline from top center to bottom center
mirror polyline at whatever angles gives you the proper # of spokes.

or are you trying to do this in 3D?

1/13/2011 11:47:39 PM

polar array w/number of objects is waaaaaaaaaaaaay easier and faster

Spokes nigga spokes

make one endpoint of each radius the center of the circle

then for n radii, in a circle of radius r centered at the origin, where one radius is in the positive x-direction, the other endpoint for the jth radius is at

(r*cos(2pi*j/n), r*sin(2pi*j/n))

where j ranges from 1 to n

then rotate and translate the whole thing to wherever you need it

just eyeball it, there's not an "easy" way.

After you have the spkes, draw some circles for the hub and trim all the lines in the middle of that circle.

Polar array. just draw one spoke and polar array helps you copy and rotate it, you just tell it how many copies you want and choose a point to rotate the spoke around. gl.

for real though, i use autocad EVERY DAY and this is the best I could do.

Put everything on layer 0.

^^ That dog won't hunt, son.

1/14/2011 9:12:16 AM

that's no dog. that's a bike wheel.

can't do it in SolidWorks either.

Took my longer to upload than to draw.

Draw a big circle
Draw a small circle
Draw a horizontal line through the middle
draw a vertical line through the middle
Draw a chord from each of the previously drawn lines (i.e. inscribe a square in the big circle)
Draw a line from the midpoint of each chord through the middle of the circle
Draw a chord to each of the new lines (ie draw a 12 sided polygon inside the big circle)
Draw a line from the midpoint of each of those chords through the middle of the cirlce
Delete construction lines
Trim all lines in the middle of the small circle.

...i don't see it. is it upside down?

1/14/2011 9:20:44 AM

that looks like one of the parachutes we had in elementary school pe

1/14/2011 9:20:50 AM

that spoke pattern would not work

1/14/2011 9:21:55 AM

don't listen to these jokers about polar array... i just tried it and i think it divided by zero or something

1/14/2011 9:23:25 AM

^^Your spoke pattern wont work >:|

jethromoore clicked the "spirograph" option. don't do that.

I THINK I GOT IT
