Adding Stackups
You can add new stackups by repeating the workflow. The same dimension can be part of two or more stackups. In the Stackup Details table, 
appears next to such dimensions. To open the list of stackups in which the dimension is used, place the pointer on .

If two or more stackups share features and dimensions, there are restrictions when modifying the stackup.
• You cannot reorder the shared features.
• Adding a new feature in one stackup that is already used in another is restricted, because, this results in reordering in the stackup that contains the feature.
These restrictions ensure a consistent part-level dimensioning scheme across all defined stackups.
On the Stackup Details table, click to navigate to the Summary of 1D Tolerance Stackups table. It provides a summary of all the analyses performed. You can navigate to multiple stackups to understand how a shared dimension influences the respective stackups.
