get_user_cart_coord

This function retrieves the pose and reference coordinate system of the specified user coordinate system (iReqId). It returns detailed information such as the coordinate’s origin, orientation, and base reference.

This function is available in M2.5 or higher versions.

Definition
DRFLEx.h within class CDRFLEx, public section (line 978)

LPUSER_COORDINATE get_user_cart_coord(int iReqId) {
    return _get_user_cart_coord(_rbtCtrl, iReqId);
};

Parameter

Parameter Name	Data Type	Default Value	Description
iReqId	int		The ID of the user coordinate system to be retrieved. Must correspond to a valid user coordinate previously defined using <set_user_cart_coord>.

Return

Value	Description
LPUSER_COORDINATE *	Pointer to the structure containing the user coordinate information.

Example

#include "DRFLEx.h"
using namespace DRAFramework;

int main() {
    CDRFLEx drfl;

    // Define and register a new user coordinate system
    float pos[6] = {10.0f, 20.0f, 30.0f, 0.0f, 0.0f, 0.0f};
    int coord_id = drfl.set_user_cart_coord(0, pos);

    // Retrieve the coordinate system information
    LPUSER_COORDINATE coord = drfl.get_user_cart_coord(coord_id);

    printf("User Coord ID: %d | Origin: (%.2f, %.2f, %.2f)\n",
           coord_id,
           coord->_fOriginPos[0], coord->_fOriginPos[1], coord->_fOriginPos[2]);
}

This example creates a user-defined coordinate system, retrieves its stored pose and reference information using the coordinate ID, and prints the origin position.
