Why a curved region was built as facets instead of on its surface.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BoundaryNotPlaced

Its seams or corners could not be placed on its surface and its neighbours’ within their tolerance.

ReachesPast

Its face, built, reached past the triangles it replaces: its boundary closed on the wrong part of the surface.

TurnedIn

Its face, built, faced into the material, against its triangles.

VolumeOff

The body it is part of did not hold its mesh’s volume, within what its curved faces may add over their facets.

FoldedSeam

One of its seams folded back in its chart, deeper than the seam’s tolerance.

Overlaps

Its face overlapped a face beside it.

MeshesOpen

Its face’s own mesh did not meet its neighbours’: the solid would not tessellate closed.

BuildFailed

Building its face, or meshing or measuring it once built, failed.

BoundaryOpen

Its face’s boundary did not close: a wire’s edges did not meet end to end, or did not close in its surface’s chart.

Crosses

Its face, built, passed through another face of the solid or through itself, away from the edges they share.

SpansShort

Its face, built, had a pcurve standing farther off an edge than the edge is long.
