Convert SDF world made with building editor to URDF
I'm using ROS Melodic and Gazebo 9.6.0.
I will use Gazebo's Build Editor to build a building using a floor plant image, like this:
You can see how it can be done in this video.
I'm going to use that world with ROS, but its format will be SDF, and I need a URDF file.
Do I need to convert it to URDF or I can use it in SDF format?
