Std ToggleClipPlane/es

A clipping plane is a plane that divides the object space in two half spaces. All object parts in one half space are visible, parts in the other half space are invisible. The objects look like sliced and interiour details become visible. The clipping plane is activated by the View → Clipping plane menu.

Show non hollow solid
Solids are shown hollow if Clipping Plane is activated. To show a non hollow solid a work around could be used. Change the Lighting of the solids View Object from Two Side to One Side and the inne part of the solid will be totally black.

Another possibility would be to leave the Lightning Two Sided and change the color of the inner solid by activating Menue Edit --> Preferences --> Display Enable backlight color. But with this the shading effect will be still there. See Forum Thread http://forum.freecadweb.org/viewtopic.php?f=3&t=4371&start=20#p94850
