Scale to an area instead of by a percentage

[toney.lowery]

Thanks for taking a look at this question...

I have a spline (created in another program and brought into ACAD) that I've covented to a pline. It is ALMOST the correct size but not quite. It's supposed to be 1502 and it's 1532.6763. When I scale it by .97998541 it's 1471.9377

So...

Is there a way to tell the object to be 1502 (+/- 0.5) and have ACAD figure out how to scale it?

Thanks in advance,

Toney

Scale to a reference.  After executing the scale command and getting a base point type r for reference.  You can then select the current length and then scale to the desired length.

It's 1532.6763 and you scaled it 97% how can it get larger to be near 1502 ?

I don't have a reference other than I know it's supposed to be 1502 in area.

Sorry 0.97998541% (less than 1)

[olivier.eckmann · Accepted solution]

when you apply a scale factor, area is multiplied by scale*scale.

So your scale factor should be sqrt(0.97998541) = 0.9899419887166284006797489124332
