CATIA 3DEXPERIENCE 2022x: Activating the Specification Tree

September 20, 2022 Mark Potrzebowski

When working with CATIA models within the 3DEXPERIENCE platform, new users often find themselves in a situation where the model “dims” are no longer selectable. If they try to pan or zoom, they notice the specification tree moves but the model does not. This situation is caused by the specification tree becoming activated and the model becoming deactivated. This video describes how that happens, why it can be useful, how to fix it if it is happening unexpectedly, and how to keep it from happening again.

Topics covered in my video demonstration include:

What does it mean to activate the tree or model?
Activate the tree or model by selecting the tree.

Activate the tree or model by selecting the Activate Tree View command.
Change a Preferences setting to prevent the tree from being activated by accident.
