Via the Element Information palette we can view (for example) the length of a Spline changing as we adjust it.
Useful information for something like shop drawings for radiant tubing or something where you need to know the total length of loops so they do not exceed 300' or whatever.
The problem is that the length of a Spline is not something you can show in an Interactive Schedule - at least not without writing some sort of code/script. ( or can you ?)
So what would that script/code/Expression.... look like, and more importantly, where/how do you get it into the program? I would like an Interactive Schedule for showing the lengths of Splines. It seems possible since that information is so easily displayed in the Element Information Palette.
The closest solution to this problem is to use Add-On from Goodies called "Polyline Accessories". The Add-on is reading information about polyline and inserts into GDL object. By processing this data it is possible to get length of the polyline in GDL script and show it in schedule.
Not super-elegant solution, but at least something.
