Arc

The arc command is available on the takeoff popup menu or the takeoff menu when taking off boundaries, topsoil strip and re spread regions, contour lines and areas.

Creating an arc requires entering three points, the beginning of the arc, a point on the arc and the end of the arc. At the start of an object all three points must be entered. After the start, the last point entered is treated as the beginning of the arc, and only two more points are required.

When taking of areas and design lines, an elevation can be entered for the start and end points of the arc. Intermediate elevations along the arc will be calculated by SiteWorx/OS.

A prompt for the point being entered will be shown at the lower left of the window in the status bar.
