MATLAB: How to connect a simscape block with add_line

add_linepmcportsSimscapeSimscape Multibody

Hey there, I want to connect a PMC port in SimMechanics automatically with a Matlab-Script. Using the 'add-line' command works fine for common simulink-connections, but not for Simscape-ports. For example if I want to connect the block 'World Frame' with 'Rigid Transform' I use
    % code
add_line('mysystem','World Frame/1','Rigid Transform/1')
But then I always get the message:
Invalid Simulink object name: World Frame/1
Does anbody know how to connect these ports in a good way?
Thanks in advance, Thomas

Hi Thomas,
add_line() works with Simscape ports. You have to refer to the ports differently. Try this command:
add_line('mysystem','World Frame/RConn1','Rigid Transform/LConn1');
There is a submission on the MATLAB Central File Exchange that shows how to use MATLAB to automate the construction of a SimMechanics model. The submission "SimMechanics Model from MATLAB Code" shows how to add blocks and connect them using MATLAB commands. The same commands work for Simscape blocks, too.
