Surface > Edge Continuity

The EdgeContinuity command evaluates how well two surface edges meet position (G0), tangency (G1), and curvature (G2) tolerances. It provides visual feedback in the viewport and lets you adjust the display parameters and required tolerances.

Steps

  1. Select two edges to evaluate.

  2. Set options in the Edge Continuity panel.

Edge Continuity Options

Add edge pair

Selects a pair of edges to analyze.

Remove edge pair

Removes a pair of edges from the analysis.

Remove all edge pairs

Removes all evaluated edge pairs from the analysis.

Evaluate

Choose the continuity level to analyze:

G0 - Positional continuity (edge distance).

G1 - Tangent continuity (direction match).

G2 - Curvature continuity (curvature smoothness).

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

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

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

Display Settings

Controls how the analysis is visualized.

Distance / Tangency / Curvature scale

Adjusts the scale factor of the deviation hairs for the selected continuity type (G0, G1, or G2). Increasing the scale factor exaggerates the hairs, making small deviations easier to see.

Sample Count

Sets how many points are evaluated along the edge pair.

Pass / Fail / Max colors

Defines the colors used to show where the edge pair falls within tolerance (Pass), exceeds tolerance (Fail), or reaches the worst deviation (Max). Click the color swatches to customize the colors.

Show Labels

Displays a label to mark the location of the maximum deviation.

Tolerances

Threshold values used to judge whether the edge continuity passes or fails.

Distance (G0)

Maximum allowed positional deviation in model units.

Tangency (G1)

Maximum tangent-angle deviation in angle degrees.

Curvature (G2)

Maximum curvature deviation. The reciprocal of radius (in model units) for absolute curvature, and a ratio for relative curvature.
