sometimes you will need the show the detail of parts from frontview which is in backside. so you have to change the some properties like visibility , hidden lines, cut or dont cut. in overload properties window you can change this properties by selecting parts and editing their properties. you can do some of them in product (assembly) properties in drawing tab. but if you do this in product, the part will have same properties in all views in drawing. but in overload properties window you can select the part one by one in each view.
