Precise dimensions and tolerance information are vital. Assembly drawings must indicate

how parts align and fit, specifying allowable deviations to ensure components function

together without issues.

3. Proper Use of Layers and Line Types

Using layers strategically allows drafters to separate different parts, annotations, and

reference geometry. Line types such as hidden lines, centerlines, and section lines

communicate depth and internal features effectively.

4. Bill of Materials (BOM) Integration

An organized BOM listing all components, quantities, and specifications is often included

alongside the assembly drawing. This helps procurement and manufacturing teams track

required materials efficiently.
