I am trying to export three shapefiles to svg files but the problem I could not make these shapefiles polygon to black outlines to be export to svg files. How do I do that ?
I tried to run that in ArcGIS 10.1 but it failed.
Shapefiles don't store any information about how to represent the data, only the geometry and attributes of the data.
As best as I can tell, SAGA only allows you (using the 'Export to SVG' tool) to export the geometry of a feature, and doesn't allow you to change the appearance of the exported SVG.
You can export the layout of a map as SVG in ArcGIS using the Export Map tool. If you're layout only consisted of a view of your shapefile(s) with the symbology you need, the resulting SVG should be appropriate.
See the ArcGIS help for more information.
