[preeti.kumari9TBN6]

I have the viewpoint and I want to get the data of the <viewer> tag from it. How can I calculate it or get the values under viewer field.

public partial class exchangeViewpointsViewViewpointViewer
{

private decimal radiusField;

private decimal heightField;

private decimal actual_heightField;

private decimal eye_heightField;

private string avatarField;

private string camera_modeField;

private decimal first_to_third_angleField;

private decimal first_to_third_distanceField;

private decimal first_to_third_paramField;

private byte first_to_third_correctionField;

private byte collision_detectionField;

private byte auto_crouchField;

private byte gravityField;

private decimal gravity_valueField;

private decimal terminal_velocityField;

I want the data for all these fields.

Hi @preeti.kumari9TBN6 ,

Could you please explain your issue a bit more using screenshots?

Hello @naveen.kumar.t 

When we export the viewpoint, it exports in the XML format and we get the viewer data. I want to get this data through API to create this XML file of viewpoint.

This is a viewpoint and I want to fetch each piece of information to create this XML with API. I can able to get the camera data but not the viewer data.
