Re: scale help
|
First 1 inch = 2.54 cm and not 2.56. Sorry for this mistake. But I guess it's not the problem.
All the lengths stored in Sweet Home 3D are in centimeter, and all imported and exported lengths are considered to be expressed in centimeters, except for Collada/DAE files containing a <unit> element. When displayed at screen (i.e. in the plan, in the furniture list or in modification dialog boxes), these lengths are divided by 2.54 then converted to the displayed text, if you chose the inch unit in the preferences. As OBJ files contain only values without any unit (open an OBJ file with a text editor if you want to see it yourself), sharing the lengths they contain from a software to an other can cause some scale conversion problems as you noticed, according to the default unit system of each software. According to this thread, I'm not sure that Blender has a default unit system. If you want to create OBJ files in centimeters with Blender, then draw a 1 unit cube in Blender, export it and import it in Sweet Home 3D. This will give you the scale factor you should use in Blender, if any.
