Convert command

Changes the structure of a curve to polyline or arc segments.

Steps

number-1.pngSelect curves to convert.

number-2.pngSelect options.

Options

Output

Arcs

Converts the curve to arc segments. Sections of curves that are nearly straight are converted to straight-line segments.

Lines

Converts the curve to polyline segments.

SimplifyInput

Yes

Combines co-linear line segments and co-circular arc segments.

Simplifying ensures that NURBS curves that consist of arc and line segments are split into proper arc and line segments making the conversion to arcs and lines more accurate.

Note: The simplification step is done using the absolute and angle tolerance, not the custom tolerance settings set in the command.

No

Simplifying can be too aggressive, converting normal NURBS curves into arcs or lines, especially if the curves are very small in relation to the absolute tolerance. In that case turning off simplifying may give a better and more accurate answer.

DeleteInput

Deletes the original geometry from the file.

AngleTolerance

The maximum angle between segments at endpoints.

Specify 0 (zero) to allow non-tangent arcs. The output will have kinks, but since it consists of arc segments, there will be fewer segments than if the Lines option was used. This is useful for approximating a curve with the smallest number of segments.

Tolerance

The tolerance at segment midpoints, overriding the system tolerance setting.

MinLength

The minimum segment length. Specify 0 (zero) for no minimum limit.

MaxLength

The maximum segment length. Specify 0 (zero) for no maximum limit.Options

OutputLayer

Specifies the layer for the results of the command.

Current

Places the results on the current layer.

Input

Places the results on the same layer as the input curve.

TargetObject

Places the results on the same layer as the target surface.
