A parametric modeler, i.e. every major CAD system in use since 1995, allows you to specify your dimensions based on formulas that use relationships between components. If you look at Solidworks or CATIA and think "man it must be slow to point and click to set dimensions" you are missing how it is actually used in professional practice. The difference between point and clicking dimensions in those tools and how they are supposed to be used is greater than the difference between pecking in Notepad and being a power user in Emacs/Vim.
