Let's go back to the "Drawing parameters" dialog box. The “Polar tracking” tab allows you to configure the characteristic of the same name. "Polar tracking", like "Object reference tracking", generates dotted lines, but only when the cursor crosses the specified angle, or increments of it, either from the origin coordinates (X = 0, Y = 0), or the last point indicated.
With “Object Reference” and “Polar Tracking” activated, Autocad shows trace lines at the angles specified in the dialog box. In this case, given the configuration of the previous video, from the last point used. If we want it to show trace lines at different angles, then we can add them to the list in the dialog box.
In the same way as “Object Reference Tracking,” “Polar Tracking” also allows you to point to more than one object reference and will show the intersection of the temporary polar tracking lines that are derived from them. In other words, with this characteristic, when drawing a new object, we can point to a reference to objects ("end point", "quadrant", "center", etc.) and angular vectors will emerge; Then we point to another reference of another object, with which we will see the angular intersections that arise from the tracking of both points.
Thus, we will insist on the fact that these 3 joint tools, "Object Reference", "Tracking ..." and "Polar Tracking", allow us to generate the geometry of new objects very quickly from what is already drawn and without detriment of precision.
