length value out of attractor points

hello everyone!

I'm having problems with a deffinition where I use 3 different attractor points to stract values for scaling curves and asign length to a SDL line in order to form pyramides...

The distance method (between attractor points and centrids) is working fine when it comes to stablishing the scale factor or the curves, but I'm running into problems when it comes to getting the lengths for the lines. I get a warning message saying that the SDL "L" input was unable to collect data... when I compare the data from the distance def and that from the lines themselves, it seems to be compatable...

I've run out of ideas... can someone help?

Thanks a lot.

I'm attaching the files (GH 9.012 & R5)

Cheers!!!
