I'm using Gazebo 9.6.0 and ROS Melodic in Ubuntu 18.04.
I have this launch file:
<launch>
<include file="$(find gazebo_ros)/launch/empty_world.launch">
<arg name="world_name" value="$(find mybot_gazebo)/worlds/odom_bot.world"/>
<arg name="gui" value="true"/>
</include>
</launch>
And this world file:
<?xml version="1.0"?>
<sdf version="1.6">
<world name="odom_world">

I have added a model (named Closed_room) did with Building Editor, but when I launch it, it doesn't show the model.
If I open the world with Gazebo, without using the launch file, it shows the building.
Do you know why?
