- Yes. If the geometry is continuously changing and caching is on,
- the cache will be constantly rebuilt, thus possibly decreasing performance.

-
- Yes. You should usually enable caching in the separator above any static
- or rarely changed geometry.
-
- If you want to constantly move a static object, put the transform outside
- the cached geometry.

- For more information on caching, see the Inventor Progamming Guide
