Heya,
I find that 'export layout to model' just doesn't work.
My work around is thus;
Publish the wanted layout to a .pdf, either the entire set of layouts/drawings or as a single one.
Open a new drawing and use 'pdfimport' command & right click < file >
Navigate to said pdf.
Select sheet/layout in question.
ok
wait.......blue bar at bottom right can move slowly.
Then modify drawing as required - check any scaling issues that may arise. nuke. purge etc.
save as.
Would love a function for this purpose.
Cheers
Jobe
