Finally,I am writing a skill code which increases poly length by 0.015 for the picture attached.
polys=setof(sh cv~>shapes sh~>lpp==list("poly" "drawing"))
dblayerTile(cv "active" polys)
but all the polys are getting increased by 0.015,in few cases there is an increase of 0.01(which is double)
so,I dont know how to go about it.
