dependencies between distances - aim of exponential distances

Hey guys,

Sorry for asking a stupid question concerning dependencies between two distances.

In my file I have two distances, which are at the same time my factor for scaling.

My Objects are scaled and rotated ellipses, their planes are on an evaluate curve.

My aim is to have min. Distance on the left side (0,0,0) and a exponential distance in x- direction.

This should also concern the smaller and rotated ellipses.(scaled and rotated by the distance as factor)

The second Problem is that they shouldn´t lie in one plane ( different distances)... but the cull pattern didn´t work any more.

Thank you for listening and hopefully answering ;)

Best regards,

Leonie
