.stl not supported in fuerte-gazebo ? [closed]

edit

Hi,

I am trying to spawn few furniture models in my gazebo world. I am using gazebo in ros-fuerte. I tried them all in ros-electric-gazebo, simple to complicated mesh, .dae or .stl, everything worked but I am have problems spawning them in fuerte-gazebo. And I am getting why they occur.

1. Some models do not appear at all, be it collada or stl, they do not appear at all.
2. Some models do not appear as collada but when converted to stl using MeshLab the appear gigantically like this. (Somebody please give me 2 upvotes, I am not able to post images!)
3. Only one model appears properly as of now like this.

What is the catch ? Why are they erratic ? All the models I have tried so far have worked properly in electric-gazebo.

This is my code in .world file:

<link name='WorkroomChair2_body' gravity='1' self_collide='0' kinematic='0'>
        <origin pose='0.000000 0.000000 0.000000 0.000000 -0.000000 0.000000'/>
        <collision name='WorkroomChair2_top' laser_retro='0.000000'>
          <origin pose='2.475 7.05 0.045 0.000000 -0.000000 0.000000'/>
          <geometry>
            <mesh filename='rtable.stl' size='0.500000 0.650000 1.300000'/>
          </geometry>
          <surface>
            <friction>

            </contact>
          </surface>
        </collision>
        <visual name='WorkroomChair2_visual' cast_shadows='1' laser_retro='0.000000' transparency='0.000000'>
          <origin pose='2.475 7.05 0.045 0.000000 -0.000000 0.000000'/>
          <geometry>
            <mesh filename='rtable.stl' size='0.500000 0.650000 1.300000'/>
          </geometry>
          <material script='Gazebo/Red'/>
        </visual>
      </link>
    </model>

Thanks!
