Problem: Large assemblies take a long time to traverse.
Proposed Solution: Assembly tree traversal is a problem that can be parallelized by allowing concurrent threads to have thread-safe access to each component and its underlying data structures (geometry, parameters, etc...). PTC indicates that at this time "calling TOOLKIT functions from different threads of the application is not supported." This is a request to enhance TOOLKIT to support calling TOOLKIT functions specific to assembly traversal from concurrent threads.
