Hi all

I have been experiencing a problem were my derived part does not update, or prompt to rebuild.

- I create a start part, save it (call it A).

- Then insert the saved part ( A ) into another new part ( B ) were i design from. I will then create configurations sketchs and features.

- If any change is made to the original part ( A ), the new part ( B ) does not prompt to rebuild or have any errors.

- So a typical case will be when select rebuild and certain bodies will update then.

The problem comes in wen i do not know when i need to rebuild.

Is this possibly a bug or functioinality? 

Has anyone else experienced this?
