Guide point out of crossed lines

[biesiek]

Hello,
I use Leica disto s910 laser to create 3d room models.
After taking maeasurements I get 3d dxf/dwg file with points marked as 2 crossed lines (no way to change this).

To proceed I need these points marked as simple sketchup guide points, any idea how to add a guide points to a middle of 2 crossed lines?

Pictures should explain what I mean

I get this

Whereas I need this

There will be a lot of the points so I need some way to mark all these lines and add a guide point into middle of each one
I'll appreciate any help given

Thanks

Meantime I've managed to find a plugin which solves the case - tomtom, tt_guide_tools-1.4.1, maybe it will be usefull for someone as well.
However if you have any other ideas - please let me know.
