How can i use RViz measure tool to get dimensions of all the complex shapes in my model. Or is there any other method to do so?

Problem solved. I actually overlaid the catkin workspace (using its catkin tutorials on ros website)on the top of existing one and then sourced it. Then opened my urdf file in rviz and everything went fine. However, i still don't fully comprehend the solution. #Jarvis I couldn't implement your solution but I think this would have also done the job. Thanks a lot for helping.

I was unable to open some urdf files in rviz with errors like 'could not find stack/package' 'cannot load model'. To check if they are opening in MoveIt i installed ROS hydro. urdf file is still gave the same error. However, along with that i was unable to open urdf files (that worked fine with groovy initially) in both groovy and hydro. In hydro the error was same 'could not find stack/package' while in groovy it was

ERROR: the config file '/opt/ros/groovy/stacks/robot_model_tutorials/urdf_tutorial/urdf.vcg' is a .vcg file, which is the old rviz config format.
   New config files have a .rviz extension and use YAML formatting.  The format changed
   between Fuerte and Groovy.  There is not (yet) an automated conversion program.

Now, i have uninstalled hydro but groovy is giving same errors and my urdf files in rviz are still not opening. Please help.

I have some urdf files of surgical robot Raven. When I open it in RViz I get the error :

[rospack] Error: stack/package raven_visualization not found [librospack]: error while executing command [ERROR] [1383833639.703512879]: Could not load resource [package://raven_visualization/Raven_files/left_arm/wrist.dae]: Unable to open file "package://raven_visualization/Raven_files/left_arm/wrist.dae".

Please help!

I followed the tutorial 'overlaying with catkin workspace' and the problem is solved, though i still don't understand what was the problem. Any possible explanations?

i followed urdf tutorials under ros documentation and ran this:

roslaunch urdf_tutorial display.launch model:=06-flexible.urdf gui:=True

As a result rviz opens and it's visualizer is pitch black. I also checked RobotModel option in add in lower left corner. I then tried changing fixed and reference frame to base link. But robot is still nowhere to be seen. There is still this big black thing in 3D model. Please help. I have ROS groovy on Ubuntu 12.04.
