If a region contains lakes or islands, and you convert that region to a polyline, the polyline has multiple sections. Each lake or island comprises one section of the polyline. When you convert a circle or ellipse into a polyline, the polyline contains 102 nodes. When you convert an arc into an ellipse, the number of nodes depends on the starting and ending angle of the arc. If the arc spans 180 degrees (for example, the starting angle is zero and the ending angle is 180), a polyline based on the arc will contain 52 nodes; if the arc spans 90 degrees, a polyline based on the arc will contain 26 nodes; etc.
Displaying Distance While Drawing Objects
If the Ruler window is active, the Ruler command shows the distance when drawing or selection commands are being used. The Ruler window shows the current segment distance, as well as a cumulative distance. If necessary, a rubber banding line displays to show what points are being used to compute the distance. The type of object being drawn or used for selection determines whether the rubber-banding line displays.
To open the Ruler window, on the HOME tab, in the Windows group, click Tool Windows, and click Ruler from the list. To then work with the Ruler command, on the MAP tab, in the Options group, click Map Tools, and click Ruler.
When you choose a new command, you may want to close the Ruler window.
The commands that show an additional rubber banding line are on the SPATIAL tab:
- In the Create group, click insert. The commands are Arc, Ellipse, Rectangle, and Rounded Rectangle.
- In the Selection group, the commands are Marquee Selection and Radius Selection, which are in a selection list.
