does anyone knows how to use ConditionalPathPoint to build muscle?i 'm stucked at its property of connectSocket_coordinate().

Based on the doxygen documentation (
https://simtk.org/api_docs/opensim/api_ ... 13a8fa369b), the ConditionalPathPoint::connectSocket_coordinate() method would be called by passing in a reference to the coordinate, something like this:
Code: Select all
model = osim.Model('modelFilename.osim');
state = model.initSystem();
coord = model.getCoordinateSet().get(5);
// ...
myConditionalPathPoint.connectSocket_coordinate(coord);

am i corrcet in using ConditionalPathPoint::connectSocket_coordinate() method? and what should i do to add the conditionnal pathpoint to the pathpointset of the muscle?

I think it would be something like this:
Code: Select all
BIClong.updGeometryPath().updPathPointSet().cloneAndAppend(BIClong_point9);
I've used upd... methods here but the get... versions should work equally well in Matlab.

i used get...method before, and it had same error with upd...method.
and do you know how to solve this problem?
