Hi again sorry to be a pain but I do not understand the scale factor of imported file to inches, you should use a 2.56 reducing factor.

A sweet home cube when imported into blender altough the cube has four seperate objects each one was 100m in length compaired to a blender cube which is 2m in lenght and a complete object.

here are some other units:

daz studio 1 unit = 1cm

hexagon 1 unit = 1cm

blender 1 unit = 50cm

unity 1 unit = 1 meter

So if the unit cm is used to store the lengths within the program what is the lenght of a standard cube when exported?

From my testing a standard cube from sweet home comes into blender at 100 meters in lenght.

But a standard cube in blender is only 2 meters in lenght.

I am unsure if blender uses a default scale when exporting models but I think thats why if i load a model from you and tweek it and reimport it into sweet home it works at the correct size.

Idealy i wish to model in blender but at the correct scale for use within sweethome if you can help many thanks!!
