Create Best Fit Profile Dialog Box

Input Data

Input Type

Specifies the type of source objects (AutoCAD Blocks, AutoCAD 3D Polylines, AutoCAD Points, COGO Points, or Surface Profile, Feature Lines) from which to create the best fit profile.

Weeding Options

Opens the Best Fit Profile Weeding Options Dialog Box, which enables you to specify options for adding or removing vertices when using either feature lines or AutoCAD 3D polylines as the input data.

Path 1

Specifies that the profile is created through a single path of regression points.

Use this option to create a profile from centerline sample data.

Path 2

Specifies that the profile is created between two paths of regression points.

Use this option to create a centerline profile between sample data of the either the edges of pavement of a road, or the left and right rails.

Best Fit Options

These options affect the manner in which the best fit algorithm is applied to the input data.

Maximum Radius For Curve Detection

Specifies the largest acceptable radius of curves that are created from the input data.

Note

This value is an estimate. For best results, specify a value that is slightly greater than the largest known radius in the input data.

Curve Type

Specifies the type of curve (either Parabola or Circular Arc) that are created between the tangents.

Creation Settings

Alignment

Specifies the name of the parent alignment. Each alignment must have a unique name.

Profile

Specifies the name of the profile. Each profile must have a unique name.

Profile Style

Displays the current style. Click the arrow to select another profile style.

Layer

Displays the layer on which the profile object is created. Click the arrow to select another layer.

Show Report

Opens the Best Fit Profile Report Vista, which lists the results of the best fit regression, including the coordinates of each regression point.
