How can I import a 3D SketchUP file into AutoCAD 2D?

Hi Ahmad, Sorry on my late reply, Ive been so very busy this past few days.
I just want to remind you that before you can convert a SketchUp drawing to AutoCAD DWG File (*.dwg), you should have SketchUp PRO installed on your PC.
Anyways, It is very easy to export a3D SketchUp to AutoCAD2D Graphics, here's how:1.) Setup your drawing to your desired view (perspective, top or elevations).2.) Then go to File drop down menu on the upper left and choose Export -2D Graphic...3.) EXPORT2D GRAPHIC tab will appear on your screen.4.) In the EXPORT TYPE: drop down menu, select AutoCAD DWG File (*.dwg), but before you hit the EXPORT button, pick OPTIONS.5.) DWG/DXF HIDDEN LINE OPTIONS tab will appear on your screen.6.) In the EXTENSION LINES, uncheck Show Extensions, if you don't and you hit the EXPORT button, those crazy construction lines will also appear in your converted .DWG File.7.) After unchecking the Show extensions, click OK.
Then click EXPORT.
Done! Blessings, Adrian
