[ros-users] Collision definitions in .model files (in gazebo)

Recently, I've been using cturtle ROS and it's ogre/ode/player/gazebo 
simulation environment for my robot.  After successfully constructing 
the kinematic, collision, and visual model of my robot, I am now 
focusing more on the room in which the robot will operate.

My question is how/why some things in environment models are collision 
enabled, and others aren't.  For example, I have two STL models that are 
both loaded into the world in the same way (via .model files).  One of 
them (the one representing the room walls) seems to automatically result 
in collidable walls.  The other basically allows the robot to move right 
through it as if it weren't even there.

Any ideas?  Is this a question I should ask somewhere else?  If so, where?
