Thank you grimmy,
It is a good suggestion but I happen to have way too many features in the pattern and the table have no equation capability. I did the calculations in excel ant tried to copy and paste them and it didn't work. In all case thank you and I'll let you know if I can figure this out.
I need to generate a patter of non equidistant features in pro/e. The distance between each feature is function of a variable that increments with constant values. For example, imagine that the distance between each feature is defined by following equation.
d1 = x * tan(x/H)
where H is...
