Any way to export to dwg without it decomposing everything to tiny lines?

As the title says, is there any way to export to dwg either from SketchUp or Layout without ending up with a drawing composed of hundreds of thousands of lines that then slows vectorworks to a crawl?

thanks!

Use the 3D export option - that maintains the entity structure

Thanks, really that simple!?

It will still export a hidden line plan view, just as entities?
