Calculating your garage etc. in Unity - a complete tool Obstacles?

I would really like to know if it is possible to create a drawing tool where you can build your own garage/chimney etc. in Unity and then automatically calculate the masses of what you have drawn.

I have looked into Google sketchup and LEGO: http://ldd.lego.com/en-us/download/ to find inspiration. IKEA also has a kitchen planner that enables you to draw your own dream kitchen. Is it possible to do something similar in Unity and could someone help me with finding similar cases where this has been done?

If this is possible, would it be too technically complicated for the users or could you easily make a user interface that everyone could become accustomed to?

At last, if this is possible, could you extract an excelfile or similar from the drawing you made which again provided calculations?

It is possible. It may not be easy, but it is possible. One way is that you could do some drag and drop interface and give each item a set mass. A chimney should be easy because you could set a mass to each cubic unit and find the volume of the chimney. A garage shouldn’t be too hard, either.
