Hi Eng.Ayad Mohsen, the shadow range in Build mode is non-adjustable.
However, if you would like to temporarily preview your scene in Build mode with a adifferent shadow range, you'll need to add a Shadow effect in Photo/Movie mode, adjust the Sun shadow range slider and click on the Build with effects button in the top left corner to preview the result.
Regarding the missing Clip plane, this was re-instated in an earlier 3.x update, so you'll have to download and install the latest version to get this functionality back.
