How To Effectively Prepare An Assignment On Architecture Drawing Office Management

• Designer
• Draughtsman
• Tracer
• Section leader
• Checker

Discuss in details the qualities, functions, and qualifications of a designer

1. to originate and finalize designs for a proposed product to satisfy the function, cost, manufacture, and market requirements in consultation with production engineers, industrial (artistic) designers, purchasing specialists, customers, and other interested persons.
2. to advise the drawing-office staff on technical difficulties.
3. to ensure that the product, after it has been manufactured, is functional, reliable, and easily maintained. A designer may hold the post of chief draughtsman or drawing-office manager.

What is the qualification and functions of a chief draughtsman?

1. to organize, direct, and co-ordinate the work of the drawing-office and its resources.
2. to determine staffing, promotion, and necessary training for junior staff.
3. to co-ordinate the activities of drawing-office staff – section leaders, design and detail draughtsmen, checkers, tracers, etc.
4. to advise staff on technical problems.
5. to liaise with other departments inside the firm and with people outside the firm.
6. to examine design specifications provided by a designer.
7. to instruct section leaders on the distribution and detailing of work.

What are the roles of a section leader?

The section leader is usually a technician engineer supervising a small team of draughtsmen and is directly responsible to the chief draughtsman. His or her main functions are:

1. to distribute work.
2. to make sure that work is satisfactory and completed on time.
3. to arrange for completed drawings to be checked, traced, reproduced, distributed, and stored.

What are the main functions of a detail designer or design draughtsman?

A design draughtsman is usually a technician engineer with a higher technician certificate or diploma. His or her main functions are:

1. to prepare the general-assembly drawings from a design layout.
2. to calculate the main dimensions and masses of components, if required.
3. to decide on tolerance fits, threads etc.
4. to consider materials to be used and methods of manufacture.
5. to prepare working specifications for detail draughtsmen, indicating overall measurements and functional requirements.

What does a draughtsman do in a drawing office?

A draughtsman is usually a technician with an ordinary technician certificate or diploma. His or her main functions are:

1. to prepare detailed drawings of individual components, parts and sections.
2. to insert on drawings production guidance and information, tolerances, materials to be used, surface finish, heat treatment, etc.
3. to calculate detail dimensions.
4. to prepare a parts list.
5. to arrange for completed drawings to be checked, traced, and reproduced for use as working drawings in the production department.

Who is a checker and what are their responsibilities?

The checker is usually a technician, and his or her main functions are:

1. to check finished engineering drawings to ensure that all specification requirements have been met, all dimensions and tolerances have been shown, and all information has been inserted regarding manufacture, materials to be used, surface finish, heat treatment, etc.
2. to check the accuracy of dimensions.
3. to ensure that safety has been considered.
4. to make sure that all parts will function correctly and are easy to manufacture. Finally, the checker refers drawings back to the draughtsmen for ratification.

What are the functions of a tracer?

The tracer's main functions are:

1. to make tracings, usually in ink, of the original drawings.
2. to insert additional detail, if instructed.
3. to refer drawings to the print room and then to file drawings, tracings, and copies of drawings if required.

Drawings are traced in order to improve the quality of prints and also to make a more durable record of original drawings. Every draughtsman and tracer should know about the different methods of drawing reproduction, in order to get the best possible prints from his or her drawings.
