Once you have a populated skeleton model, it can sometimes be difficult navigating through all the features. Luckily, there are some good out-of-the-box ways Creo can handle this.
An easy way to remove unneeded features showing in your skeleton is to turn off any extraneous datums. For example, if you only have coordinate systems in your skeleton model, turn off axes, points, and planes.
Zoom To Selected
If your skeleton is large or difficult to navigate, using the Zoom To Selected feature is a good way for the Creo window to zoom to the selected feature (shown below). This works great for surfaces and standalone datums!
However, Zoom to Selected won't work for copied internal or external geometry (CG or ECG) datums. If a placement coordinate system was used and brought into the skeleton as a standalone datum, you can zoom to this and find the dependent features from there.
The Search Tool is an incredibly powerful, underused Creo feature. Simply type CTRL+F in a Creo model and you can find almost anything you need to in your models.
