increasing and decreasing a value in a pattern?

ive created a datum curve of which i want to pattern around the edge of the solid protrusion.

Easy enough, direction 1: angle enter increment value



View attachment 47



the only problem i want the datum curve to increae and decrease in length as it rotates around the solid protrusion...

i can get it to increase by using the second direction of the pattern..

select the length and enter the increment value but how could i make it decrease in length while rotating round? Do i need to add a constraint eg a maxium or a relation?



Im a little stuck... is it possible?



Many thanks
