Maybe you can try something of the form

pts=[[1,2,3],[1,1,1],[2,3,0]]
line3d(pts,color='red')+point3d(pts,color='blue')

You will probably need to plot each of the line segments separately.

Update: Removed bug on 2nd line of code.code and added a last line (curiously P.show() does not actually show the plot in cloud.sagemath.com).
