Cut out curves on a half cylinder

[dacaputo]

Sketchup Make 17.2.2555. How can I cut the profile in blue into the half cylinder (shown in red on the cylinder)?

You can use JPP. Or extrude a flat shape and then use Shape Bender

Many different ways to go about this. Here is a non extension, non solid tools method that will work in any version of SketchUp available.
