# Synopsis

PDX_MSGT igeo_ApproxSetPointType(int type)

# Purpose

Set the approximation type of point data to approximate

# Description

Sets the approximation type of point data to be created during linear approximation. By default the point type is set to IGEO_POINTS_3D for the creation of 3D model space points.

# Input

## type

### IGEO_POINTS_3D

Create 3D model space points for approximation

### IGEO_POINTS_3D_2D

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

# Return

          IGEO_NOERR
          IGEO_NOAPPROXDATA
          IGEO_INVALIDPNTTYPE
