Shortcuts
In addition to the availability of magnetization common to all the creation modes (grid, vertical/horizontal directions), it is possible to have detections of the orthogonal straight lines in the polyline creation mode.
They correspond to the directions at 0° and 90° as to the previous segment.
These directions are accessible by using the SHIFT key during the creation of a polyline.
