SincpacC3D General Information Command Summary PtArc |

Description

The **PtArc** command displays the arc distance, radius, and delta (central) angle of the arc segment defined by picking three points. Points may also be specified by keying in point numbers at the prompt.

Usage

Type **PtArc** at the command line, then follow the prompts. You will then see output similar to the following:

The **PtArc** command has two different modes of operation:

**Single**: Used to measure single arcs at a time; the start point, point-on-curve, and end point must be selected for each angle.**Multiple**: Used to measure multiple angles, all from the same initial starting point and point-on-curve. Begin by selecting the first two points. Then, the arc data is displayed for each successive pick. Right-click to select new starting point and point-on-curve.

The "Single" and "Multiple" keywords may be used to switch between the two modes.

You may also type the point number for a Cogo Point at the prompt, instead of selecting a point on-screen with the cursor.

Displays the angle formed by three points. The angle dimension is displayed as an interior angle, an exterior angle, and a deflection angle.

Displays an inverse between two points, containing the Horizontal and Slope distances, the bearing, the slope and grade, and the Delta X, Delta Y, and Delta Z values between the points. It can also maintain a running total of successive distances, adding the value of each measurement to the running total. Points may be selected on-screen, or by typing Cogo Point numbers at the prompt.
