hello i'm back now,

why i do polyline: because it's importante for base(low point) but curve it's good but always control if error point or add poin or ecc.. for me it's long time = attention or precise or add... so polyline it's base where i can point and perfect point place..but i'm not good explain you because i'm not good english ok i will show you pic or movie for example(tutorials for moi) okbut not soon but lately ok?
