Exporting to DWG Full Scale (1:1) Model Space, Model Geometry Only cannot be unticked

[inventor1K5NLB]

Hi, 

I am trying to export a DWG created in Inventor (it's a DWG due to our work template rather than .IDW) and am exporting this to Autocad with correct scaling. I know my best option is to use the 'Full Scale (1:1) - Model Space' option but when I want to untick 'Model Geometry Only' I am unable. 

I need to untick this as I want to include section views etc. Does anyone know why this is happening or a workaround?

You can always save it ass an inventor deg, then in autocad export the layout using "ExportLayout".

if you export with that checked, what do you obtain?
