Mastering Complexity with 3D MethodologyEvolution – System Engineering

Unit configuration (>=30 years ago) Product Line (20 Years ago) Platform (10 Years)

Each Unit drawn Standardization: product line with standard layout for representatives, system mapping introduced

Rising Complexity: explosion of local requirements, development of regional codes & standards lead to higher number of variances One size doesn’t fit all anymore, ‘regional touch’ must be locally implemented

2D CAD

Mastering Complexity with 3D MethodologyBefore

Inputs• Calculation

sheets (excel)• Manually

2D Layout Assembly• Geometrical

information• Range coverage

(min. / max. / ISO sizes)

• E.g. Range 4000 possible configurations

• Checked 80 rep ca.2%

• Time 1W for 1 Rep including all calculations

2D Output• 2D Layout

drawing• Views• Tables


Mastering Complexity with 3D MethodologyToday: automatic dispo-layout generation & collision detection at top level
