Prepare CAD file before import it into Revit

[hliS658H]

I  imported a CAD file into Revit but it is invisible or it might be too small to be seen; So I am trying to fix it in AutoCAD;  when I use Zoom/Extents, the drawing covers the full screen; but when I use Zoom/All, there is much more empty space. This might be the reason the drawing was invisible after I brought it into Revit?

I found a solution by using limit and draw a rectangular around the drawings to reduce the limit. But still it doesn't show properly in Revit.

I use wblock to get the drawing into a new file and the problem is solved.
