# Synopsis

PDX_MSGT igeo_Get102Continuity(long option, MDA_PTR db_ptr, double *cont_toler, int *continuity)

# Purpose

Get the IGES composite curve (102) continuity.

# Description

Determines the minimum continuity between all the segments in the IGES composite curve entity to within the cont_toler tolerance. The continuity value can vary from -1 for discontinuous to a maximium of 2. The IGES composite curve must be a valid IGES definition.

# Input

## option

### IGEO_GTEST

Test for G continuity for derivatives to 2

## db_ptr

The IGES 102 entity database pointer.

## cont_toler

The continuity tolerance. The distance between the derivatives must be less then or equal this value to have derivative continuity .nf [0] = Model Space Distance (G0) [1] = Radian angular difference (G1) [2] = Curvature difference (G2) [3] = Normalized derivative difference .fi

# Output

## continuity

The level of continuity (-1 to 2).

# Tolerances

NORMAL_MAG_TOL

# Return

          IGEO_NOERR
          Low level error return
