How do I show control handles on shape vertices?

[stevek]

Hello,

MS has made such a mess of all their programs that I literally can't figure out which Visio version I have. It's part of a 365 subscription and it's the Professional edition.

I've been using Visio for about 15 years and I STILL don't know how to make the shape handles that control the curvature of a line segment between two vertices show up. For example, I drew 4 free-form line segments. I snapped the vertices at the ends together, then used union to close the shape. Great. But now I want to modify the curvature of the lines but I don't have the handles to do so. I can select and move the vertices, but I can't modify the two handles that I think each vertex has.

How do I show them?

Bonus: Is there a way to insert a vertex into a line/curve segment?

Thank you for any help, it will be greatly appreciated!

Use the Pencil tool.  The inflection points become visible with this tool.
