Hi everybody, I am using the node xml2factor_walls from the gazebo pkg to spawn the walls of a map. The file ".model" is this: true -16.5 -16.5 0 factory_map.png 2 200 1 false 0.08 0 0 0 Gazebo/White The thing is that I have to do same changes to make this map in gazebo to has the same size that the one I am having in rviz, for doing that I need to know exactly what each parameters means. I have check the gazebo project website, but I couldnt find it. Someones knows what are those parameters of the model file. Thanks in advance. Nicolas
