# Synopsis

PDX_MSGT gdx_SetLinearApproxPntsPerSeg(int number_of_points)

# Purpose

Set the current GDX linear approximation tolerances.

# Description

Set the linear approximation tolerance for the current GDX linear approximation workspace. The tolerance must be greater than 0.0 unless the approximation method has be set to number of points per segment (set gdx_SetLinearApproxMethod).

# Input

## tolerance

The linear approximation tolerance.

## number_of_points

Number of points per segment.

# Return

          GDX_NOERR
          Low level error return
