# Synopsis

PDX_MSGT gdx_SetLinearApproxPointType(int type)

# Purpose

Set the current GDX linear approximation type of point data to approximate.

# Description

Set the linear approximation type of point data to be created during the linear approximation for the current GDX linear approximation workspace. By default the point type is set to GDX_POINTS_3D for the creation of 3D model space points.

# Input

## type

### GDX_POINTS_3D

Create 3D model space points for approximation

### GDX_POINTS_3D_2D

Create 3D model space and 1D/2D parameter space points for approximation

# Return

          GDX_NOERR
          GDX_NOAPPROXDATA
          GDX_INVALIDPNTTYPE
