Each view is a stored as a block for use in AutoCAD. Open it in Autocad and use the 'Insert' command. Select the desired view and explode.
Alternatively, the UNGROUP command can be used to explode the view group.
What's your exact problem?
Are the section view geometries wrong?
Could you attach the source Inventor idw, generated AutoCAD dwg file and the image snapshot with the problem highlighted?
Open as Read Only Inventor DWG file in ACAD (since ~ ACAD 2010 or 2011 ?).
Type _exportlayout and press <Enter>.
Save & open new (model space) file.
Edit drawing in ACAD (explode or Block editor etc.).
P.S. I use "exportlayout" way only for simple task (drill / end points for CNC). I finish all my drawings in Inventor only.
