I am getting error when i am, importing assembly from the invent. I am having error at the joints and also the parts imported doesn't import data regarding inertia or geometry. When i run the simulation, I am getting this error

Caused by:
Error evaluating parameter 'Mass' in 
Unable to resolve the name smiData.Solid. 
Error evaluating parameter 'CenterOfMass' in 'NewTestAssembly

Thank you

Sorry i have to hide few names due to some technical issue

I am getting the axact same error when I run my code. Did you manage to resolve this error? Any help would be appreciated!

I was running into the same issue and solved using the following. I am assuming you have already imported from a .xml file and generated a [xml_filename]_DataFile.m that has been saved in your directory (if you have not, run smimport('filename.xml'), where filename is your unique filename). In the matlab command window, you can run

run('filename_DataFile.m')

which will then create a smiData object in your matlab workspace that Simscape can pull from.

As an example, if I have an xml file named robot.xml, I would run

smimport('robot.xml')

in my command window to import the geometry to simscape/simulink. This will automatically generate a file named robot_DataFile.m in my current directory. It will also initialize the smiData object. However, if you are running again or Matlab has lost track of the smiData object, you can run

run('robot_DataFile.m')

to reinitialize the smiData object and you should be good to go from there!
