To edit an existing element in Arc mode
- Select Insert Element.
- Select Arc from the Mode option menu.
-
Specify the portion of the element to be changed by entering two data points.
The former line string is removed and a double rubber band is attached to both points specified. The solid rubber band tells where new arcs are to be defined.
-
Enter two data points to define one arc.
The arc will be defined by the first point entered in step 3 and the two points entered in step 4.
If you press Reset after one data point, step 4 is started again.
After one arc is defined, a dashed rubber band displays between the end of the arc and the second point specified in step 3.
-
A line is drawn between the end of the last arc and the point where the dashed rubber band was connected. The modified element is then placed as a complex chain.
