If your screen gets cluttered with old entities or stray lines, or you have made changes that are not reflected, you may need to regenerate the screen.

Regenerate

Menu: View / Regenerate Shortcut Key: Ctrl+R Toolbox Icon:

Redraws the entire drawing in wireframe form. This erases any shaded or hidden-line areas of the screen. This command affects only the active view window.

Regenerate All

Menu: View / Regenerate All

Shortcut Key: Ctrl+Shift+R

Redraws the entire drawing in wireframe form in every open view window. It erases any shaded or hidden line areas of the screen.

Regenerate Double Line Entities

Menu: View / Regenerate Double Line Entities

Toolbox Icon:

Redraws all of the double line entities in the drawing. Sometimes deleting a line or entity that intersected a double entity will give the appearance that part of the double entity was erased. This command refreshes the double entities, removing any apparent gaps.
