Keeping one object stationary and inserting that into rotatable object .

Hello all, I am having some problem about insertion of one 3D object into other 3D object. For that one object must be stable and another one must be rotatable . User should insert that according to his view. Like we keep drill machine stationary and rotate the object then we insert the drill machine into that . How to implement that into MATLAB ? thanks.

Create an hgtransform and parent the display of the rotating object to the hgtransform. Leave the non-rotating object parented to the axes directly, or else create a different hgtransform to parent it to (might be useful for proper positioning.)

To rotate, set the Matrix property of the hgtransform to the proper transformation matrix.

The proper transformation matrix will probably be a combination of three matrices: one to translate the object so that its center of rotation is at (0,0,0); the second to rotate a centered object; and the third to translate the center of the rotated object back to the original location.
