Goal: Refresh the Mechanical tree. This is needed for certain operations that visually appear only after an update of the tree.

Code:

Tree.Refresh()

The Tree.Refresh() method accepts a boolean value that controls whether the states of data model objects are recomputed before the tree is refreshed. This boolean has a default value of False. For more information on updating the state of the data model, see Recompute the State of Data Model Objects.

You can also pause the tree from updating while doing a long-running script, such as the your-script example below.

Code:
