Hi all,

I've been playing with blender and managed to model a desk i want to use in a plan.

The model is to scale in blender at 160cmx120x73cm

I export the model and import it, however it seems to think there is a bunch of empty space in the imported model. As such when i try to set the size in sweet home 3d its not correct as its resizing the empty space.

I'm a bit stumped, can anyone help?

Link to my blender file, an example exported obj and the mtl file and the screenshot if it helps to work out what im doing wrong.
