Manipulated the Bezier Curve Tool

[DaveR]

I would expect you would find it in the Context menu when you right click on a Bezier curve.That’s what is indicated in the instructions.

Select an existing Bezier curve drawn/edited with the Bezier Curve Tool from the SketchUp team and use Manipulate Curve directly in the Right Mouse Button context menu to activate the tool.

Are you not finding it there?
