Rotating dynamic components

But I couldn’t find it. According to the Sketchup tool description (http://help.sketchup.com/en/article/160379) it should be available through my View menu, but there is no Dynamic Components there.

Is it an extension that I need to download?

It is a standard extension distributed with all versions of SketchUp. However, you must activate it via the Preferences->Extensions dialog before you can use it.

You should then be able to select View->Toolbars->Dynamic Components to make the DC toolbar visible, and then select the interact Tool (icon like a pointing hand) on the toolbar. The Interact Tool should also be somewhere on the Tools menu.

That did it, Steve. Thank you.
