dwg accuracy out of Layout is not 100 percent.
I researched that, and reported my findings here: Import_export precision in Layout
In and out of sketchup, and from sketchup to Layout, its 100%.
But out of layout to dwg, and also dwg directly into Layout, is more like 99,999 %
Some revisions to my matrix attached. Scalp exports are not that useful, as they dont include your Layout dimensioning and text.
