Reference and Constraints with AutoCAD - Section 3

CHAPTER 10: TRACKING OF REFERENCE TO OBJECTS

"Object Reference Tracking" is a valuable extension of the "Object Reference" characteristics for drawing. Its function is to make lines of temporary vectors that can be derived from existing "Object References" to signal and obtain additional points during the execution of drawing commands.
In other words, while we draw and once we have activated the references, Autocad generates timelines - which are clearly distinguished from the rest by being dotted - that allow you to “track” the location of new points. If we activate more than one reference, then what we will obtain will be more than one tracking line and even the intersections that arise between them, as if they were new objects and their respective references.

You should also note that each trace line also has a label where it displays the relative polar coordinates dynamically as we move the cursor so that we can capture points at specific positions marked with those tags. Even once the address of a new point has been established with respect to the reference used, it is possible to capture a distance on the trace line directly in the command window. Let's look at a new example.

In the "Drawing parameters" dialog box, in the "Object references" tab, we can enable or disable Tracking. Although, as we showed at the beginning, we can also do it in the status bar. In turn, the behavior of visual tracking aids, called Autotrack, is configured in the "Options" dialog box on the "Drawing" tab that we have used before.
