Importing .dwg file

when I import .dwg file (that is in 2D) in sketchup it get 3th dimension (height), it does not hapend for all lines but 90% of them does
please help!

I have never seen SU add 3D to a file that has none, so the information must already be there, for instance the Thickness property of lines might not be zero. DWG is basically a 3D format too, and for example digital maps often come with the contours placed at the correct 3D elevations.
If you want your DWG flattened, you have basically two options: Use the Flatten command (part of "Express tools") in AutoCad, or in Pro version of SU import the file, select Plan View, turn on Parallel Projection and re-export the file as DWG from the File>Export>2D Image menu. Now a re-imported file should be fully 2D.
If this didn't help, post the DWG if possible, and someone will have a look

It's possible for what looks like a 2D CAD drawings to be 3D. Lines can have thickness and have different Z values for their ends ! View it in ISO in CAD to see this... Sometimes 3D contours at the right Z are useful later...
Assuming you really want a flat 2D import... use the AutoCAD 'Flatten' command on the dwg, then select all lines (use quick-filter), get properties and set their Thickness=0 - also in the dwg delete any text, dims, hatching etc that you don't want (can't import anyway) and also delete any stuff that's in paper-space; then purge, audit etc - save_as and then you can import it into SUp...
