Can I trace an existing Line or Area while digitizing?

Many of our iOS apps provide the function for manually digitizing Point, Line and Area Features. While digitizing a Line or Area Feature, there is a way to incorporate part of an existing Line or Area into the new Feature. Simply tap on the “Include Line/Area Boundary” icon in the digitizing screen then tap on the existing Line/Area. Then, you will be prompted to tap on the starting and ending nodes of the segment to include. The existing Line/Area could be a previously digitized Feature or a line or polygon that you have imported from Shapefiles.
