Hi guys, my goal is to realize a multibody simulation of a vehicle whose CAD assembly has been provided to me. I do not want to use parametrized blocks to create the geometry of the vehicle in simscape, since the suspension scheme is pretty peculiar of the prototype which I am working on. I have imported the geometry using the solidworks plugin and now I have a full vehicle which I can correctly visualize in the Simscape mechanical explorer, made by solid objects and transforms (not more than these). I should now procede adding the road to my model, but I do not know specifically how to do that. I can not find online any guide or tutorial which can help me. I found this example https://it.mathworks.com/matlabcentral/fileexchange/64648-matlab-and-simulink-racing-lounge-vehicle-modeling-with-simscape-multibody in which wheels are modeled as parametrized boxes, which is not what i need.
Can you give me some more useful sources or hints on how to continue my work?

Hey Massimiliano,
Maybe the following templates will be of use:
https://www.mathworks.com/solutions/physical-modeling/simscape-vehicle-templates.html
https://www.mathworks.com/matlabcentral/fileexchange/79484-simscape-vehicle-templates
The templates should allow you to "Test your designs against realistic road profiles by converting GPS data into 3D road definitions." It should allow you to create custom variants that you can replace with the imported Solidworks geometry.
