Picture sketch is a tool used in Solidworks to insert a picture on a plane. Using this as a reference sketching is done. You can download blueprints from here: drawingdatabas... #Solidworks #Blueprint #Sketching
While inserting picture on top and right planes, position of the picture can be taken as mid-plane i.e. placing the picture in the center of the plane. By doing this surface modelling will be easier.
