Bottom up design with components placement.
This method involves step-by-step creation of assembly components and its subassemblies starting from the bottom level and to the top level. Assembly components at all levels are created and edited in separate windows. Models are developed independently, based on pre-defined requirements for the composition of the assembly and its design. After insertion, components in the assembly and its subassemblies are positioned using matings.
This method applies in the following cases:
•scope and design are clear in the beginning;
•most of the parts and assemblies were developed earlier (for example, library elements or elements borrowed from other assemblies).

1.Creation of parts |
•parts files are created; •In part files, the required build operations are executed. |
||
2.Creation of subassemblies, insertion of components in subassemblies |
•– subassembly files are created; •– components are inserted in subassemblies; •required matings are imposed on components |
•If subassemblies are included in higher level subassemblies, the actions of this step are repeated in higher level subassemblies. |
|
3.Creation of an assembly |
•– file of the developed assembly is created; •prepared components are inserted into the assembly; •required matings are imposed on components |
