Building Objects with AutoCAD - Section 2

5.7 Polygons

As the reader surely knows, a square is a regular polygon because its four sides measure the same. There are also pentagons, heptagons, octagons, etc. Drawing regular polygons with Autocad is very simple: we must define the point of the center, then the number of sides that the polygon will have (obviously, the more sides the polygon has, the more a circle will appear), then we must define whether it will be an inscribed polygon or circumscribed to an imaginary circle that had the same center and radius and, finally, we indicate the value of the radius. Let's see it in the video.

It should be mentioned that the polygons are actually closed equilateral polylines (that is, with equal sides and where their initial point, whatever it is, coincides with its final point). The polylines in Autocad are a special type of object that allows us to create shapes with more agility than the objects studied up to now in the individual. But the polylines and their creation are a topic that will occupy a part of the next chapter, although it is worth mentioning this characteristic of the polygons in Autocad, because being also polylines, they share with these diverse characteristics that serve us for their editing, as we will see later .

 

5.8 Points in object perimeters

Now let us return to the subject with which we began this chapter. As you will recall, we create points simply by indicating their coordinates on the screen. We also mentioned that with the DDPTYPE command we can select a different point style for display. Now let's look at two more options for creating points on the perimeters of other objects. These points are often very useful as references to create other drawings.
The DIVIDE command creates points on the perimeter of another object at intervals such that it divides it into the indicated number of parts. For its part, the GRADUA command places points on the perimeter of the objects in the intervals specified by the distance captured.
