# Intersect Crv/Crv

In this Grasshopper Tutorial I will use the Intersect Crv/Crv tool to produce a parametric structure. First I will linear Array a line and then intersect it with two set of parametric polylines. Then I will move the intersection to produce the parametric model.

Hi Gravitas1

You can convert them to mesh and then use the weaverbird window plugin to give them a border and then use the thicken mesh command
