Parametric Assembly Modeling
Assembly modeling is used to combine components to create a 3D parametric assembly model
A component is either a part or a subassembly of parts
Essential tool for a work group developing a product composed of multiple parts
Relatively new (1990’s)
Used extensively in automotive and aerospace industries
Assembly Modeling Tools
Assembly modeling tools are used to:
Combine components to create assemblies
Specify location and orientation of components within an assembly constraints
