In Rhino you can just select a bunch of curves (lines) and type Length&lt;Return&gt;. Since I construct a lot of wireframes I sometimes do a SelectAll&lt;Return&gt;Length&lt;Return&gt; just to see how many feet&#x2F;miles of lines I&#x27;ve drawn. I thought it was a fun novelty to do that at the end of a project– partly because I don&#x27;t know how if it would be so easy in other software.
