Working Drawings are often confused with shop drawings and vice versa. Following is the key difference according to my understanding:
1. Working drawings are those issued by the designer/ Architect to the contractor. Such drawings are usually the final stage of design process. That is why working drawings are also referred to as 'Final Design Drawings' or 'Construction Drawings'. Working drawings contain enough detail to fully describe the character of the structure to be built and enough for the contractor/ bidder to estimate the amount of time, labor, material, and equipment needed to complete the work. That is why, sometime, working drawings are also stamped as 'Issued For Construction'.
2. Whereas Shopdrawings are those which are usually prepared by the contractors at site or at their Technical Office based on the Working Drawings and according to the detail required by site personnel for a particular piece of work. Many a times, the Engineer/ Site Supervisor/ Consultant demands certain shopdrawings for approval prior to actual construction. It is difficult to predict exact number of shopdrawings for a construction project in advance. Experienced site staff can work with high-level detail. At times, for smaller projects, no shopdrawings are produced by the contractor. They rather rely on Construction Drawings only.
SHOP DRAWING : are made by contractor according to the site situation and demand of site and submit it to the Client or Consultant for approval
WORKING DRAWING : are those on which u have to work such as excavation, buildings structures etc and it is provided by the Client or Consultant approval to contractor p.s shop drawings after approval of client or consultant also consider as working drawings
I agree with the explanation of Samiuddin M with the exception that some shop drawings may require the approval of client whereas others may not. Example of shop drawings not requiring approval may include drawings prepared on the request of a fabrication shop foreman who wants to hand over some nitty gritty details to his fabricators so that they don't mess up.
A nice question & I agree with the previous answers
A shop drawing is a drawing set of drawings produced by the contractor check Examples of these include: elevators, structural steel, trusses, pre-cast, windows, appliances, cabinets, air handling units, and millwork. Also critical are the installation and coordination shop drawings of the MEP trades such as sheet metal ductwork, piping, plumbing, fire protection, and electricalExamples of these include: elevators, structural steel, trusses, pre-cast, windows, appliances, cabinets, air handling units, and millwork.

Working drawings by a designer\\architect\\engineer , while shop drawing are usually made by a contractor and include specific construction excution layouts (eg. blown-up door schematic)
Working Drawings
Drawing that is subject to clarifications but is complete with enough plan and section views (with dimensions, details, and notes) to enable the depicted item's construction or replication without additional information.
Shop Drawings
A shop drawing is a drawing or set of drawings produced by the contractor, supplier, manufacturer, subcontractor, or fabricator. Shop drawings are typically required for prefabricated components.
I agree with MR FAYSAL USMAN . It,s perfect
different because the drafting makes the image in accordance with the sktesa given a design engine engineering
Contractor take tender drawing from consultant after then contractor modify as per require and submit as a shop drawing. after Approval Contractor modify and send to site that is working drawing.
