About Viewing Changes to a Part
You can view the changes that were made to a part or feature in the current session. The changes are compared to a baseline of the model when it was retrieved. Changes to features in the part appear with different markup in the View Changes Tree.
Features that contains changes from one explicit value to another value are displayed as Changed. An example is changing the depth value in an Extrude feature from one value to another value. Changes that cannot be expressed in terms of specific values both before and after the change are displayed as Modified. An example is changing the reference that defines the depth of an Extrude feature.
Only design related changes are shown. Changes to simplified representations, environment, appearance, style, and views are not shown.
