Synopsis

PDX_MSGT gdx_CurveMeshToPLCurveMesh(long option, MDA_PTR gdx_db_ptr, int model, double tol, int num_pnts, MDA_PTR *gdx_cm_ptr)

Purpose

Approximate curves under a Curve Mesh entity with a polyline

Description

Approximate curves under a Curve Mesh entity with a polyline Underlying curves are passed to the gdx_CurveToPolyLine(). See the gdx_CurveToPolyLine for detail.

Input

option

GDX_APPROX_BY_TOL

Approximate the curve by the given tolerance

GDX_APPROX_BY_NUM_PNTS

Approximate the curve by the given number of points

GDX_APPROX_BY_NUM_PNTS_PER_SEG

Approximate the curve by no more than the given number of points or to within a tolerance for each segment

GDX_APPROX_BY_NUM_PNTS_OR_LINEAR

Approximate the curve by the given number of points unless it is linear

GDX_APPROX_BY_TOL_AND_MAX_LENGTH

Approximate the curve by the given tolerance and the length of each segment should not exceed the 10 times of the given tolerance

gdx_db_ptr

A GDX curve mesh data base pointer

model

Destination model

tol

The approximation tolerance (may not be used for some options)

num_pnts

The number of points (may not be used for some options)

Output

gdx_cm_ptr

A GDX curve_mesh data base pointer

Return

      GEA_NOERR
