1. Create and Combine an Area (Region) • Region is a two-dimensional enclosed area solid. You can create the closed loop solid that is made of lines, polylines, circles, arcs, ellipses, elliptical arcs, and splines by suing Region Command. The object shown in fig.1 is made of four lines and four arcs. These lines and arc have not common endpoint. They are eight individual objects. Fig.1 Fig.2 Fig.2 is a enclosed area solid object and is a closed loop That is made of lines and arcs by Region Command. Regions can be used for • Applying hatching and shading • Analyzing properties, such as area, using MASSPROP • Extracting design information, such as the centroid or center of gravity
2. Drawing Pattern by HatchCommand line:HATCHa.Click Draw menu Hatch or.Drawtoollab. In your drawing, specify a point inside each area or pick up the areaboundary that you want hatched, and then press ENTER, This pointisknown as the internal point.c. In the Hatch and Gradient dialog box, Hatch tab, in the swatch box, verifythat the sample pattern is the pattern you want to use. To change patterns,select another pattern from the Pattern list.To see how the hatch pattern willlook, click the[...J button next toPattern. Click OK when you finishpreviewing.d. You can also define a simple line pattern using the current linetype replacingpredefined hatch pattern.f. Click OK.Island detectionIsland displayHormalOuterOIgnore
2. Drawing Pattern by Hatch a. Click Draw menu Hatch or . b. In your drawing, specify a point inside each area or pick up the area boundary that you want hatched, and then press ENTER. This point is known as the internal point. c. In the Hatch and Gradient dialog box, Hatch tab, in the swatch box, verify that the sample pattern is the pattern you want to use. To change patterns, select another pattern from the Pattern list. To see how the hatch pattern will look, click the [.] button next to Pattern. Click OK when you finish previewing. d. You can also define a simple line pattern using the current linetype replacing predefined hatch pattern. f. Click OK
