multipe offset curve by percentage

[cowski]

I want to offset a curve (line) by 0.25 then the next offset to be 110% of that distance (0.275) and the next to be 110% of the new distance (0.3025) etc, etc ad nauseum. There must be an easy way to do this. I have tried formulas in both the transform command (translate - copy) and in the offset curve command to no avail. The closest I got was to use transform - scale. I had 2 lines 0.25 apart and used 1.1 as the scale factor (the midpoint of the first line was the invariant scale point) but it only moved the line 0.025 (10%) rather than the 0.275 (110%) that I was expecting. The line also gets longer using the scale command, which is not really a problem in my case.

An update (just in case anyone is interested):

By carefully selecting options in the geometric progression point set I'm pretty sure I could get points spaced the way I wanted. From there it would be a matter of copying lines using point to point option - much less tedious than calculating distances and typing in delta offsets.

Plan B was to make a grip program to do what I wanted (though I avoided this since it looked like a one time application).

In the end it all worked out since the proposed change was cancelled anyway.
