By Baldemar Garcia And Luis Dominguez Top Down Assembly By Baldemar Garcia And Luis Dominguez

Top Down Assembly consists in creating an object and all its components in just one long process. starts by constructing the main part which will be used as a reference to make the rest. when finished all the components will appear as if they had been created individually.

Disadvantages Complicated steps to create a piece. Difficulty in making changes to references in assembly. All references are automatically changed when a piece is modified. It is suggested to start with the biggest component and plan accordingly.

Advantages Better view and control of placement. Insertions can be done to create a piece/assembly. Pro Engineer create dimensions for the user. The user chooses the reference planes.

To begin Begin a Top Down Assembly by going to new > assembly. To start with the creation of a piece go to insert > component > create > solid > name of piece | create features.

Click on part and solid click ok. Then click on create features.

2nd step Next step is to choose the sketch and the reference planes. To create a part follow the regular method.

Other Parts To continue working with the rest of the components, it is necessary to activate the window. This way every part of the assembly will be treated as a single feature. To create the rest of the parts always start by insert > assembly > create.

Advice Make use of tools learned previously. For example, the shell and extrude tool were used. Follow the same process to create the rest of the components using your knowledge in Pro-E.

Top Down Assembly Top Down and Bottom Up Assembly can be used simultaneously to perform better in the creation of objects.
