AutoCAD Inventor :: Best Settings For Exporting DWG

Client supplies template for acad with title block c/w attributes that eventually get populated via their doc management system.I open template in inventor, drop in views from me model, then dimension & annotate.I have previously created styles in inventor so all layers, text etc is correct. And colours used match clients ctb file.

I then export to acad 2010 dwg using sheet to layout with best visual fidelity and the acadiso.dwt as a template.I then open in acad and add my bits into title block.

I check layer manager as quite often inventor converts acad colour 'red' to a RGB colour code in inventor; so these need resetting.Then repair or delete and redo dimensions that have not come over well.However, I now have everything on paperspace - not ideal. Ideally I would like everything in modelspace at 1:1.

I have tried other setting sin export and it just doesn't work.What is the best way and best settings for this export? I will adapt my workflow to suit best way.
