Assume we have the following complex class diagram.

To perform impact analysis:

Select File > New Diagram > Others > Matrix Diagram to create a matrix diagram.
You can specify the scope for the generating the matrix in either Project level, Diagram level or Model/Package level. Let's create the matrix in Project level.
Let's create matrix base on the relationships of classes. Select Class in both Column and Row.
Then select Relationship in the By combo box.
Let's construct the matrix based on associations between classes. Select Association in the Relationship combo box. Press OK to proceed.
The matrix diagram based on the associations between classes has been generated.
You can highlight specific column/row to see their relationship.
The order of the element can be changed by right click on it and select Move Up/Move Down.
You do not need to repeat the entire procedure to create matrix for other relationship. This can be done directly inside the matrix by selecting the Relationship combo box. Let's change the matrix to showing Generalization.
Now the matrix has been switched to become showing generalization.
To go to the element in diagram, simply right click and select Open.
The containing diagram will be opened and the shape will be focused if it only appears in one diagram. Otherwise the Show View dialog will be prompted and let you to specify which diagram you would like to open.
You can also export the matrix into excel by pressing the Export to Excel button on the right hand side of the matrix, and specify the destination location.
And here is the exported excel document.
