I want to construct semi Cylinder So I use Extrude to Prism or Cylinder Tool

Choose semi circle and input Altitude

But Geogebra constructed whole Cylinder!

you can draw a half cilinder as a parametric surface: Surface[cos(α), sin(α), h, α, 0°, 180°, h, 0, 2]

or eventually Surface[r*cos(α), r*sin(α), t, α, 0°, 180°, t, 0, h] for a half cilinder with given radius r and given height h.

Thanks for your answer. I know your method too.

I propose that Extrude to Prism or Cylinder Tool improve any shape base.
