Curve By Table Parameters dialog box

Linear Segment

Creates line segments between the data points in the table.

Smoothing Off

Applies the direct curve fit method to the data points in the table.  Using this method, the curve passes directly through the points.

Smoothing On

Applies the least squares curve fit method to the data points in the table.  Selecting this option enables the tolerance drop list.  Using this method, the curve path is controlled by the tolerance value and does not have to touch the points.

Tolerance

Allows you to specify a tolerance for the Smoothing On option.  Describes the maximum distance the curve can deviate from the points.

Specifies the units for the embedded table of points. The range of values include all possible units of length for both the English and Metric systems. Units default to the units of the QY CAD document.

Open

Allows you to specify an open curve. For example, the first and last data points do not touch each other or any part of the curve.

Closed

Specifies a closed curve. For example, the first and last data points can either touch one another or any part of the curve. When this option is set, the Periodic and Natural options become available.

Periodic

Connects the first data point with the last data point to create a smooth tangent closed curve.

Natural

Creates a closed curve without a tangency condition.

Allows you to select coordinate systems to create the curve from. The coordinate system must be created before creating the curve through table of points.

Records the total number of points in the spreadsheet.
