assembly drawing is an overall drawing of an entire
assembly of parts, a machine, or an entire factory, an
area... General drawings will be used to assemble
equipment and details, according to a certain sequence,
used to check the installed unit or will be used as a basis
for designing details and components at the design and
manufacturing stage.

1. Demonstration:
Selecting a representative shape: Similar to the detailed vector board,
the representative images on the vector board are representative
shapes: Diameter, cross-section, cross-section, excerpt, etc. The number
of representative shapes is chosen so that they are consistent. oh To
reduce waste (products, components, groups) there is no shortage.
2. Size:
- Dimensions
- Laminate size (combined lamination)
- Installation size (machine installation)
- Decent size
- Limited size

3. Technical requirements:
• Includes topics on the characteristics of compounding, methods of
compounding, procedures that can be used to create and perform the
work of the labor board, and to evaluate and evaluate Terms of use,…
• For example:
• - Indicates the wrong position when rehearsing
• -Dampening of the muscles while laboring such as: cutting, making
lace,...
• -When adjusting the valve, operate it in a clockwise direction
• -After completing the assembly, add the head to the assembly.
• -Requirements from the machine: for the machine to run without valves
at 1000 rpm/minute to check the symptoms of head, heat, etc.
• -Explain the parameters: power, transmission number, rotation
number,...

4. Position numbering:
- Plan according to a certain direction
- Make decisions according to your priorities
- Coat-based calculation
- Measure by item
- Questions to ask when determining location:
The number of positions recorded outside the symbol is placed on the
horizontal value of the line using the connection bar. This application
disappears as soon as it appears on the part's header. The position
numbers must be written in order or properly collated and must be
placed in parallel with the original name frame .

4. Position numbering:
The position number is assigned once for each element in the diagram.
If you want to re-evaluate the detailed number in a different form, you
must keep the original number and write the number below the number
in 2 lines.
If there are many similar details such as bolts, screws, etc., then only
choose one detail .
The details are combined together but cannot be combined with
multiple extensions for each item, so it is allowed to combine 1 common
extension .
