Use the Annotate tool to create a label with a leader line pointing to a specific point on the model.
If more than one object are under the cursor, the pick chooser appears. Point to the hand icon next to the object you want. Keep the mouse button down to position the reference point.
I don’t want to show the arrow from the label to the object?
Use the Locators > Move Locator tool to pick the label, then open the information window and turn off the arrow option.
