Tangent function

Hello, I recently have been forced to go from Sketchup Pro to Sketchup for Schools as a public school teacher. Could someone please explain where I can find a tangent tool to create a line from one curved surface to another with the line being tangent to each? This used to be embedded in an extension in the full version.

There is a tangent inference indication when drawing arcs connecting to existing edges but not the other way around. There is an extension called True Tangents which will create guides to indicate tangency between arcs, circles and other geometry. It isn’t a native or embedded extension.

At least at this time, SketchUp for Schools does not have an option to install extensions, though.
