Edge Continuity

The EdgeContinuity command uses hair lines to visualize distance, tangency or curvature deviation between an edge pair.

Steps

  1. Select two edges to evaluate.

  2. Set options in the Edge Continuity panel.

Edge Continuity Options

Continuity
Distance

Evaluates distance deviation between the selected edge pair.

The decimal places of distance deviation is controlled by Document Properties > Units > Display precision. (Decimal-only)

Tangency

Evaluates tangent direction deviation between the selected edge pair.

Curvature

Evaluates curvature deviation between the selected edge pair.

This option displays absolute and relative (in parentheses) deviations.

  • Absolute curvature deviation = (1/Radius1)-(1/Radius2)

  • Relative curvature deviation = (Radius1-Radius2)/(Radius1+Radius2)

Density

Controls the density of the hair lines.

Distance/Tangency/Curvature Scale

The scale factor for the hair line length based on the selected continuity option.

Curvature tolerance

The allowed curvature difference.

Tangent tolerance

The allowed tangent direction difference.

Distance tolerance

The allowed gap distance.

Good color

A hair line displays this color if the evaluated value is below the tolerance.

Bad color

A hair line displays this color if the evaluated value is above the tolerance.

Max color

The hair line with the largest value displays this color.

Labels
Show distance

Displays the largest distance deviation value in a dot.

Show tangency

Displays the largest tangent deviation angle in a dot.

Show curvature

Displays the largest curvature deviation in a dot.

Add edge pair

Click to select one more edge pair.

Remove edge pair

Click to select one of the existing edge pairs to remove.

Remove all edge pairs

Click to remove all the evaluated edge pairs.
