In pcbnew SVG files can be created by plot menu (in B&W) or export SVG menu (B&W or Color).
Export SVG menu is more suitable to create a view of a board, and plot menu is better to create a B&W document of silkscreen layers.

Note: pcbnew plot code is cleaned, mainly in dialog files, but still needs more cleanup.
