Looking for a simpler way...

[oakes3]

I want to drill a series of 100 holes along a curved vector that are not equally spaced, but get closer together as they go.

If it was in a straight line, I would use MS Excel to calculate positions then place them all by hand.
If it was a linear spacing, I would just use Aspire.

Anyone think of a way to do this?

Thinking out loud:

Can I place them on a straight vector, then bend it in Aspire?
Use Illustrator or Photoshop to make vector/bitmap, then import?
Draw it, then scan it...

Hi David,

perhaps it is wise to post a picture of what you want to make just to give us more visible info

Cheers

Hopefully this will help

Hi David,

I think a couple of the ideas you suggested in your post for getting this done may work fine.

I have had very good luck scanning images and creating the parts from them. Even CAD drawings of fabricated parts take considerable time to redraw when the .dxf or .dwg files have not been submitted, and I have found scanning the drawings to be a good alternative.
As long as you have a method to scale everything to the correct size it usually works very good.

The idea of doing the points on a straight line and then bending seems like it will work too, but I think you would want to have both the straight line and the curved lines drawn and then you could fit the straight line onto the curved line.
Someone is bound to reply with a better method, but if not I would try your previous ideas.
Do these holes have to be within a definite tolerance?

I would use PhotoShop, but that is my wepon of choice.
You may be able to use the node editing function to move a straight line to the curve you want, adding the dots before you alter the line.

hello

need to looking for the least common multiplier...

http://www.easycalculation.com/hcf.php

it is an online calculator...

given all number( lenght between neighboor point), the result can be write in the distance between circles placed on the line...
and need to erase the not necessary... circles... i heard it... it's difficult...
this way any curvature can be populated with objects(circles) even with unequal distance...

if you can give the concrete example i try to post the result...

thanks
viktor

these similar "stupidities" led to the computer...

[gravirozo]

okay... i made some mistake... i was long time in school... and it was on hungary still...

not lcm what need, but greates divider... greatest common factor sorry...

ps another calculator

This may not be any simpler.
Create several layers.
On the first layer create or import the curved line or object, and add one copy of the object to be copied.
On the next layer make 20( this number is arbitrary) equally spaced copy’s of the object along the curved line.
On each subsequent layer, reduce the number of equally spaced objects proportionately as it fits your need.
You will need to delete the unneeded extra objects from each layer.
I hope this made sense.

Thanks for the ideas!

So far this morning, I'm attacking it this way:

I put together a Word file: "o o o o o o..." with one more space between each "o".
Then I used Illustrator to draw the curved vector, and pasted the text onto the curve, adjusting the point size and letter width until it fitted.
Thats as far as I am right now.

Next step is to import into Aspire and use it as a background bitmap to guide the placing of the drill holes.

Try this... In Aspire make your letters o's like you did in Word file. Now draw your curved line that you want in Aspire. Then use the test on a curve feature in Aspire to put your 0's onto the curved line. Group the items and re size to whatever dimension you need.

use the test on a curve feature in Aspire

D'Oh!
That would be a lot easier, and save me a huge step.

Thanks!
