Hi Lars, cool sculpture! It will be fun to see a large scale version with your new shape.

Basically there are tools for specifying the size and location of things when you are first creating them.

Like for example when you draw a rectangle, there are Width: and Height: options shown in the upper-right corner of the main MoI window, and you can enter in specific values there to create a rectangle of a precise dimension.

If you want to adjust something to a specific dimension later on, probably the best way to do it right now would be to draw a rectangle of that dimension and use it as a snapping guide in the Scale command, let me know if you need any help with this.

In the future I do expect to add some additional edit tools for resizing objects to a particular dimension (of its bounding box) more easily, and also be able to add in dimension objects. But these latter will be more like annotations that help describe dimensions to people looking at your model later on (like in drawings and print outs), not really as a way to control the size.

For controlling sizes through editing dimensions, that really is the area of a different style of program like SolidWorks, Pro/E, etc... - they are built using a "constraint-based" system that allows for more of that kind of editing. MoI is not quite the same as that kind of system, MoI is a lot more kind of freeform and unconstrained. This kind of has its own set of advantages and disadvantages.
