Edges from sketchup to blender

Im having a problem importing lines as 3ds from blender into sketchup
this is what happens this

turns into this (sorry i couldnt load the image to here

basically what i want to do is import the lines from sketchup and execute the wireframe function to turn all these lines into tubes in one go because there is a lot of lines in this picture and doing it manually would take forever!
I have no idea why my edges are being turned into planes from sketchup to blender but any help at all would be greatly appreciated!
