How is the development of a pyramid similar to the development of a cone?

Question 2

Parent-child relationships are important for assemblies built using a constraint-based modeler. What problems might occur, and how could you prevent drawing management problems when deleting or changing component parts in an assembly?

Answer to Question 1

The development is similar because the lateral surfaces of a cone may be considered a cone as a pyramid having an infinite number of edges.

Answer to Question 2

If you delete a part that is the parent of some other part in the assembly, then the location of the child part is undefined. As the modeling software tries to generate the assembly from the parts and relationships stored in the database, undefined locations require you to redefine the placement of the child parts and may, in the worst case, cause the file to fail to open or the software to crash.
Using a set of datum planes as the parent part in the assembly also helps fix your assembly on the coordinate system.
