RULES AND FEATURES OF ASSEMBLY DRAWING
It is important that you follow some simple rules when producing an engineering
drawing which although may not be useful now, will be useful when working in
industry
6.1 Lay-Out of Drawing
All assembly drawings should follow a standard layout therefore interpreting and
analysis will be easier
Make your own Template follow the steps below
1- Open AutoCAD New File
2- Draw a frame according to your limits (use the size of paper you are using

TEMPLATE
6.2 Parts list
Each part is given a unique number, indicated on the drawing by a circle with the
number in it and a leader line pointing to the part. The leader line terminates in an
arrow if the line touches the edge of the component..
A table of parts should be added to the drawing to identify each part, an example of a
parts list is shown below:
PART
NO.
PART NAME
NO.
OFF
MATERIAL
6.3 Dimensions
Detailed dimensions required for manufacture are excluded from assembly drawings.
But overall dimensions of the assembled object are usually indicated
