Synopsis

PDX_MSGT gdx_FaceGenerateParmCurves(long option, double devtol, long maxits, int fitdeg, MDA_PTR gdx_face_ptr, int *status)

Purpose

Generate missing Parameter Space curves in a face

Description

Generate missing parameter space curves for the face.

Input

option

Options (Not Used)

devtol

The deviation of the model space image of P(s) from the projection of M(t) should not be greater than devtol. This tolerance should be larger than MODEL_SPACE_PNT_TOL, at least by 1 to 2 orders of magnitude.

maxits

Maximum number of iterations. Iteration will be stopped if this number is exceeded.

fitdeg

Degree used for fitting. See option GDX_FITDEGMAX above.

gdx_face_ptr

The database pointer for the GDX face entity

Output

gdx_face_ptr

An updated GDX solid with parameter face curves

status

Enumerated flag indicating whether status of parm curve generation : GDX_PARM_UNKNOWN (-1) = Generation results unknown GDX_PARM_GEN_FAILED (0) = Generation failed GDX_PARM_EXISTED (1) = Parm curves already existed GDX_PARM_GEN_CURVE (2) = Generation succeeded GDX_PARM_GEN_DEGREE_1 (3) = Degree 1 generation succeeded GDX_PARM_GEN_REV_MODEL (4) = Generation from reversed model curve succeeded.
