Feature Description
The draw line to modify line function adjusts the shape of a line object based on a newly drawn line, allowing you to quickly modify the line shape without editing nodes. It is very convenient for local adjustment of complex line objects and is suitable for many application scenarios, such as indoor workers modifying existing land class lines according to new boundary lines drawn from field surveys, or revising contour lines from preliminary curve results based on terrain. This function is only applicable to line layers.
