Modifications
Modifications are any alteration that you make to a component after a document has been created from that component. Unlike an earlier solution in which the component was merely marked as changed, you can now record the detail of when a component was altered by which action.
This gives you a tool that you can use to keep track of the intended (and unintended) alterations made to your model.
Relationship to the creation data
The relationship between component and document results in the fact that a modified component, like a document, can also be marked as changed. But there is room here for the system to be more intelligent:
Since all the modification data is recorded, particularly the reason for the modification, though moving a profile does indeed impact on the associated group drawing, it has no effect on the drawing of the individual part.
Further into the future, this relationship will also mean that it is possible that, for example, changing the material of a component only marks a parts list as changed if the parts list also displays the material.
