When I create objects I like to declare names for all the dimensions so that
I can easily adjust the model later. Often the relative placement of objects
is
calculated mathematically from these variables (e.g. to ensure tangency or
whatever).

Are there any 3D modellers that allow you to do the same thing? My
experience
is very limited with modellers so perhaps I just overlooked the feature, but
it
seemed to me that I was always required to specify precise dimensions,
without
any kind of indirection.

Not that I mind writing the script myself, but such a tool could be useful.

Windows or Linux will do.

Thanks.
