Convert Arc to Straight Lines

Use this function to convert an arc (source) into 3D polyline with a series of straight lines (more break points). The curvature of the converted 3D polyline with the source can be controlled with the parameter Accuracy.

• The source can be arc/circle/polyline/spiral.

  • The line segments of the source will be intact (no additional break points).

  • If a line is selected as the source, it will be simply changed to 3D polyline.

• The length of the sub-divided straight lines is determined by the radius/parameter (spiral) and accuracy.

• The elevation of the converted 3D polyline will be the same as that of the source.

Command prompts for:

Select a circle/arc/polyline:

Pick the source that is to be converted as 3D Polyline (program accepts only one entity).

Degree of accuracy <1.00>

Enter the accuracy number (a numeric value) that controls the closeness of the 3D polyline with that of the source.

Any value from 0.1 to 3.0 or higher can be used. For further details, refer to Accuracy in Create 3D - Line.
