Which statement is true about splitting polylength measurements?

• A. Polylengths can be split, perimeters cannot
• B. Perimeters can be split, polylengths cannot
• C. Neither can be split
• D. Both can be split

Answer: (A)

Splitting measurements works with the path structure of the data. A polylength is taken along a polyline, which is a path composed of individual segments. You can insert a split point along that path and create two separate polylength measurements that cover the portions on either side. This is a natural operation because the polyline itself is a sequence of connected segments, so dividing it simply yields smaller, valid polylengths. A perimeter, however, is the total length around a closed shape. It’s typically stored as a single value representing the entire boundary. The standard split function is not designed to break a single perimeter measurement into parts; you’d have to create separate measurements for each side manually if you want that level of detail. So while you can measure the lengths of individual edges, splitting the entire perimeter as a single measurement isn’t supported, making polylengths the thing that can be split and perimeters not.
