Best way to make wooden column from DWG?

When importing .dwg’s, I always use this extension:

Before doing the lathe, select the edges and ‘weld’ the parts that need to be ‘smoothed’.
Than run the simplify extension to reduce the edgecount.

Welding is now integrated in the context menu (rightclick on selected edges)
Check this thread, too, it’s about extrusion, but the same principle applies when doing lathes
