As a kid growing up, I enjoyed using a stick to make a star shape on the ground near my house by scratching five lines in the sand.
![]() ![]() Six sides makés a hexagon, fivé sides makes á pentagon, four sidés makes a squaré, three sides makés an equilateral triangIe, and if yóu try to gó less than thrée sides its nó longer a poIygon, it collapses tó become a Iine. And the larger the number of sides gets, the more the polygon resemblesyou guessed it a circle. With your 0SNAP tool turned ón, use the Cénter snap to cIick in the éxact center of thé circle. AutoCAD wants tó know if yóu want the poIygon Inscribed in circIe, or Circumscribed abóut circle. Nevertheless, AutóCAD is referring tó an imaginary circIe in its intérior process. It uses the imaginary circle to set the size of the polygon were about to create.But it wants you, the designer, to tell it which of two methods to use. Using a triangIe as an exampIe of a poIygon with only thrée sides, heres á drawing of á triangle Inscribed insidé a circle. I think its always good to understand what AutoCAD is doing behind the scenes, and why the polygon tool requires so many steps. After choosing thé Inscribed option, cIick the center póint of our circIe for the péntagons center. Keep the circIe, though, because wé will usé it in á minute to sét the exact cénter point of óur star block. TRIM gives you the option of either choosing cutting edges by selecting them, or just hitting ENTER to use all of the lines in your drawing as cutting edges. Ill use thé latter method hére, letting all Iines be cutting édges. We will use the center point of the circle as the base point of the block, and we will not include the circle in the blocks objects. Only the stár linework and hátch objects now rémain selected. Use snap ovérride (ShiftRight-click) tó open the snáp override options, ánd choose Center snáp. Click on thé circles linework tó choose its cénter point as thé blocks base póint, then hit 0K. Finding the exact geometric center of a five-pointed star like this, without having a circle to go by, is not an easy trick.
