Sketchup to dwg file line with nonexplode?

when i eport any file sketch to dwg i,every line become it possible sketchup to dwg file line with nonexplode ?

Use, Circle, Arc and Poligon tools. Weld the edges to Curves. Make groups, components.

Make sure to use the 3D DWG export option.

Also, in the export options turn off Faces. If you export as 3D, but leave faces turned on, you get both the true curves from the arcs and circles, and you get segment edges as well. With faces turned off you should only get the true curves.

Thank you.
It works.
