looking for a converter

hi guys,

does anyone knows if there is a converter for converting a linear scale to a circular one and vice versa ?

Could never find one... Even tried excel charts, but the resolutions were 'dodgy'

Had to resort to linear image 'dot and rotate' in photoshop = Manual Labour.
But it worked. You could also try circularise a linear image in photoshop... I haven't tried this, as i think the resulting accuracy might not be right.

i was even thinking of a CNC machine to make circular disks like this.

The only way I have done it is "brute force." I used Excel to create a table translating linear distances to degrees. Then I used Adobe Illustrator to rotate a circle and make scale marks at the zero point. Finally, I converted the stroke graphics to pixels by loading into P'shop, and saved it as a Targa.

It's easier to build the image in AI than in P'shop, but it's still all hand work.

Illustrator will convert a rectangle into a circle. (It will even convert a line into a circle.) But the scale marks do not go along for the ride.

Me too in regards to brute force. For the 3-bearing AOB finder I number crunched the linear values to angles with a spreadsheet. And plot those as polar coordinates in Autocad. Those tiny marks were a pain to do.

it is exactly this 'hand work putting marks' that i am trying to avoid here

too bad that there is no converter for such workarounds,would be very handy

thank you all guys for your replies
