Too small buildings

[bartolinciu]

I have followed the instructions and the simulation works fine, but the buildings are too small:

Can you make sure that you are not changing the scale of any component of the world? To be sure, kindly download the simulator package again from Github and launch it without modifying any of the files/folders.
If you still find the error, verify that the vehicle still moves around even though the buildings are small and get back to us. We will try to investigate more.

I am having the same issue, I have tried reinstalling the whole package but the problem remained. The vehicle is moving normally.
Using Ubuntu 18, ros melodic and gazebo 9.19.0

In my friends machine everything works normal, even though he has the same gazebo version.
As a simple workaround I have upscaled every dimension in buildings by 100 (in model and collision box) and it looks as it should. If this solution is acceptable, I could create pull request with additional folders for "big" buildings, and if someone will have the same issue, then they can just replace the folder contents to have right size buildings.

We suggest you work on the machine where the simulator works normally. Refer to the system requirements in the README. Do not scale any buildings/models/vehicles. If the issue seems to persist amongst a majority of the participants, we will investigate and announce an update of the simulator.

I have the same problem, simulation works but buildings are too small. I'm using Ubuntu 18.04, ROS Melodic and Gazebo 9.0.0

I also have the same problem, simulation works but buildings are too small. I'm using Ubuntu 18.04, ROS Melodic and Gazebo 9.0.0.

@ToToSpl Could you post the exact configuration of the system in which the simulator works? It would be great for the other participants to verify if they have all configs in place. It seems to work fine with some of our other participants.

We will try to investigate further if there are any issues in some of our other machines and post updates here soon.

I also have the exact same problem. Everything seems to work fine except from the buildings that are too small. I'm using Ubuntu 18.04, Ros melodic, Gazebo 9

It appears this problem is caused by the units in the .dae mesh for the building model. We are working on a solution that will work on all computers.
In the meantime, this issue can be temporarily fixed by manually changing the units in the mesh file. Our solution uses the mesh file that is in the Gazebo model path, so you can find and change the units with the following steps:

1. cd ~/.gazebo/models/law_office/meshes
2. vim law_office.dae (or use whichever text editor you prefer)
3. Replace the line <unit name=inches meter="0.0254"> with the line <unit name="meter" meter="1.00"/>.
   This should scale all buildings up by the necessary factor.
   Let me know if you run into any problems.
