Hi Eleni
what you are suggesting goes in the right direction. We do have a multibody example of solar panel tracking if you want some Multibody files to prototype:
Regarding your question:
We released a free blockset addon with example of blocks that connect 1D simulation with 3D simulation in Simscape:
For older release than 20a look at the link in the File Exchange entry:
There is even a DC motor with Multibody ports that you can apply to move a rotational joint:
After you have looked at the example I believe you are going to understand properly the connection of 1D with 3D. You need to create a kinematic relationship between the components, here the screenshot fro mone of the example:
Hope that helps
Vasco
