Errors that can occur during CAD operations.

Variants

StepReadFailed

STEP file read failed (invalid format or corrupted data).

BrepReadFailed

BRep file read failed (invalid format or corrupted data).

StepWriteFailed

STEP file write failed.

BrepWriteFailed

BRep file write failed.

TriangulationFailed

Triangulation/meshing failed.

BooleanOperationFailed

Boolean operation (fuse/cut/common) failed.

CleanFailed

Shape cleaning (UnifySameDomain) failed.

HelixFailed

Helix edge construction failed (e.g. degenerate parameters).

ExtrudeFailed

Extrusion (Solid::extrude) failed: empty profile, zero-length direction, or profile not closed.

SweepFailed

Pipe sweep (Solid::sweep) failed: profile not closed, edges not connectable into a wire, or BRepOffsetAPI_MakePipe returned no shape.

ShellFailed

Shell / hollow (Solid::shell via BRepOffsetAPI_MakeThickSolid) failed: thickness sign incompatible with geometry, sharp corners yielding a self-intersecting offset surface, or OCCT internal failure.

FilletFailed

Fillet (Solid::fillet_edges via BRepFilletAPI_MakeFillet) failed: radius too large for the local geometry, tangent discontinuity along the selected edge chain, or an edge not belonging to self was passed.

ChamferFailed

Chamfer (Solid::chamfer_edges via BRepFilletAPI_MakeChamfer) failed: distance too large for the local geometry, tangent discontinuity along the selected edge chain, or an edge not belonging to self was passed.

LoftFailed(String)

Lofting (Solid::loft / BRepOffsetAPI_ThruSections) failed: section count too low, section wire ill-formed, or OCCT internal failure. The string identifies which precondition or stage failed.

BsplineFailed(String)

B-spline solid (Solid::bspline) construction failed: grid too small, surface interpolation rejected the input, or sewing/capping failed. The string identifies which stage failed and with what parameters.

InvalidEdge(String)

Edge construction failed due to degenerate input (e.g. collinear arc points, zero-length line, negative radius). The string describes which constructor failed and with which parameters.

SvgExportFailed

SVG export (HLR projection) failed.

StlWriteFailed

STL write failed.

InvalidColor(String)

Invalid color string (unrecognized name or invalid hex format).

Unknown(String)

Unknown error.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
