how to draw insulation in a curved wall?

I am drawing a detailed curved wall in 2d and need to follow with the insulation pattern (its not a hatch) in to the curved part of the wall.

how exactley can I manage that?

thanks.

a quick and dirty way would be to find the centreline of the wall, convert it to a polyline, make that polyline into the BATTING linetype; adjust it's linetype scale to suit

Oooh, very easy way! thanks NBC, the problem is that now it doesnt match the one I have drawn for the rest of the wall,I have tried to change the x and y dimention in the properties , doesnt work,any other way?

Draw a single section of insulation then use array circular to copy and rotate it as it goes quick and dirty just need to know the radial angle of the single section
