HM_ExtAPI::SurfaceExtrudedGetData()

Returns parameters that define extruded surface.

Syntax

bool SurfaceExtrudedGetData(
const HM_EntityGeometrySurface & surface,
HM_EntityGeometryCurve & generator_curve,
HM_Vector& dir
);

Type

HyperMesh Ext API Function

Description

The function expects that the type of surface object is HM_ExtAPI::EXTRUDED_SURFACE(). Application should call the function HM_ExtAPI::GeomSurfaceGetType() to verify the type before calling SurfaceExtrudedGetData function.

Extruded surface is defined by parametric equation

S(U, V) = C(U) + V D,

where C(U) is parametric curve and D is extrusion vector.

Parameters returned by SurfaceExtrudedGetData Extruded surface parameters
generator_curve C(U)
dir D

If the function succeeds, the return value is true. If the function fails, the return value is false. To get extended value information, call HM_ExtAPI::GetLastErrorCode().

Requires including hm_extapi.h.

Inputs

surface
[in] - Handle to surface object that was returned by previous calls to API functions.
generator_curve
[out] - Handle to curve object that represents the curve used to generate extruded surface.
dir
[out] - Extrusion vector. The length of the vector defines parameterization scaling of extruded surface in V parameter. The direction of the vector defines extrusion direction.

Errors

None.
