Hi,
Here is my code:

+ Code Snippet

#include <DarkGDK.h>

int nObjectCube=1;
int nObjectSphere=2;

int nMeshSphere=1;

int nLimb1=1;
int nLimb2=2;

int nImageCrate = 1;

void DarkGDK ( void )
{
	dbSyncOn ( );
	dbSyncRate(60);

	dbSetWindowOn();
	dbSetDisplayMode(800, 600, 32);

	dbAutoCamOff();
	dbColorBackdrop( dbRGB(0, 0, 0) );
	dbPositionCamera(0,0,-5);

	dbLoadImage( "../Media/Crate.jpg", nImageCrate );

	dbLoadObject( "../Media/Cube.x", nObjectCube );
	dbTextureObject( nObjectCube, nImageCrate );

	dbMakeObjectSphere( nObjectSphere, 0.5f );
	dbMakeMeshFromObject( nMeshSphere, nObjectSphere );

	dbAddLimb(nObjectCube, nLimb1, nMeshSphere);
	dbAddLimb(nObjectCube, nLimb2, nMeshSphere);

	dbDeleteObject(nObjectSphere);
	dbDeleteMesh(nMeshSphere);

	dbOffsetLimb(nObjectCube, nLimb1,   1.0f, 0.0f, 0.0f);
	dbOffsetLimb(nObjectCube, nLimb2 , -1.0f, 0.0f, 0.0f);

	while ( LoopGDK ( ) )
	{
		dbSync( );
	}
}

I am getting the following render:

Normally I sould see two spheres, one on the right side and the other on the left. What I am doing wrong?

I tried your code but instead of loading a model, I created a cube with dbMakeObjectCube. It works: displays a box and two spheres on two sides.

Is it possible that the crate model you load contains more than one limb? If it has a limb 0 and a 1, then adding the first sphere fails and only the second will be added. What happens if you increase the limb indexes to 2 and 3?

Thanks for your info. I don't know how to change the number of limbs in a model.
For modeling I use the Silo and Ultimate Unwrap3D (Pro 3.xx). For the purposes of the sample above, I created a simple cube from within UU3D in DirectX 9.0 format.
For the export I have the following options:

All I want to achieve is, parent-child relationships among my models (animated or not) and I don't know how

Yes, this was the reason of the problem.
And here is my solution:

#include <DarkGDK.h>

int nObjectCube=1;
int nObjectSphere=2;

int nMeshSphere=1;

int nLimb1;
int nLimb2;
int nLimbsCount;

int nImageCrate = 1;

void DarkGDK ( void )
{
	dbSyncOn ( );
	dbSyncRate(60);

dbSetWindowOn();
	dbSetDisplayMode(800, 600, 32);

dbAutoCamOff();
	dbColorBackdrop( dbRGB(0, 0, 0) );
	dbPositionCamera(0,0,-5);

dbLoadImage( "../Media/Crate.jpg", nImageCrate );

dbLoadObject( "../Media/Cube.x", nObjectCube );
	dbTextureObject( nObjectCube, nImageCrate );

// advance to the first available limb
	dbPerformCheckListForObjectLimbs( nObjectCube );
	nLimbsCount = dbChecklistQuantity();
	nLimb1 = nLimbsCount;
	nLimb2 = nLimb1 + 1;

dbMakeObjectSphere( nObjectSphere, 0.5f );
	dbMakeMeshFromObject( nMeshSphere, nObjectSphere );

dbAddLimb(nObjectCube, nLimb1, nMeshSphere);
	dbAddLimb(nObjectCube, nLimb2, nMeshSphere);

dbDeleteObject(nObjectSphere);
	dbDeleteMesh(nMeshSphere);

dbOffsetLimb(nObjectCube, nLimb1,  -1.0f, 0.0f, 0.0f);
	dbOffsetLimb(nObjectCube, nLimb2 , 1.0f, 0.0f, 0.0f);

dbColorLimb( nObjectCube, nLimb1, dbRGB(255,0,0) );
	dbColorLimb( nObjectCube, nLimb2, dbRGB(0,255,0) );

while ( LoopGDK ( ) )
	{
		dbSync( );
	}
}
