Evaluate > Continuity > Surface continuity

Checks the positional, tangent plane, and curvature continuity between and inside surfaces.

See Check the deviation and continuity on surface edges

> Find

Positional Continuity

Only check for gaps between surfaces (labeled with "O" symbols).

Tangent Continuity

Check for gaps and tangent discontinuities (labeled with "T" symbols).

Curvature Continuity

Check for gaps, tangent, and curvature discontinuities (labeled with "C" symbols).

> Check Spacing By

Arc Length

Check the continuity at equally spaced points along the surface, determined by the Distance Between Checks option.

# Per Span

Check the continuity at a number of points in each span equal to the value of the Fitting > Curve Fit Checkpoints option of the Preferences > Construction options window.

This option only appears when Check Spacing By is Arc Length.

Distance Between Checks

The arc-length distance between continuity checks when using the Arc Length option.

Locator Persistence

If this option is toggled on, the surface continuity indicators have the ability to become a persistent locator which will update with changes to the geometry. Note that Locator Persistence only takes effect if boundaries are explicitly selected by clicking them (not by selecting surfaces with a pick box or prior to selecting the tool).

Check Interior

If this option is toggled on, continuity is checked and displayed along multiple-knot isoparametric curves in the surface's interior.

Show Max Labels

If this option is toggled on, points of maximum positional, tangency angle and curvature deviation are shown. Note however that these labels will only appear if part of the boundary has discontinuities (gaps, tangent or curvature breaks) that are out of tolerance.

Show Edge Labels

If this option is toggled on, indicators showing areas of discontinuities ("O", "C" and "T" labels) are initially displayed along the boundaries. Red symbols indicate areas of maximum discontinuity. Blue symbols indicate areas of minimum discontinuity.

Show Comb

This option only appears if Show Edge Labels is on. Toggle it on to see the comb lines for gaps, tangency breaks and curvature breaks.

Auto Scale

This option only appears if Show Combs is on. When Auto Scale is checked (default), the scale of the deviation combs is automatically calculated to be proportional to the size of the object.

When this option is unchecked, three Scale number fields appear (for Positional, Tangent, and Curvature deviation), allowing you to set the comb's scales at the time of creation.

Scale

Three values (for Positional, Tangent, and Curvature deviation respectively) that allow you to adjust the scale of the combs at the time of creation. These values are only available if Auto Scale is turned on.
