Importing coordinates using macros

I have 2D coordinate data that I need to import into a solidworks part.  I have a new part open, with units set to mm. I have created a macro and pasted my data into a sketch using the command "Set skPoint = Part.SketchManager.CreatePoint(10000, 0, 0)" .  When I open the sketch the xcoordinate dimension is "1000000.00000006mm".  Where can I find documentation on using this command and coordinate system units?
